"Easily?" Not really. Prehung units are made to slip together at the
jamb and trimming there screws that up. It would be simple enough to
trim a 1/2" off each outer side of the frame except it's very difficult
to get the casing trim off w/ tearing it up. Unless I had a bunch of
them, I'd probably just opt to make the frame for it from scratch as
being quicker and simpler. But, I've a full shop--depends on what you
have to work with...

You'd be better off with a slab door, trimmed down to fit snugly in
the existing opening.

The short answer is no. You could add a second layer of 1/2
drywall around the opening in a picture frame effect. Make it
something like 6" oversized and edge with L metal. The prehung
will now fit, the trim will work, and you have a new accent.

Yes, it can be done. Easily no.

I had 4 closet complexes where I installed both regular (7) and bifold
(3) doors. Not a problem to make your own jambs if you have a table
or radial arm saw. Rip to width, cut to length, cut a rabit on the
uprights to accept the top jamb.

Of course mortising for the hinges (if any) and latch (if needed) adds
a bit of time and fool around. I have done all that in the past with
hammer/chisel and a few times with a router.

All those doors were done over a 10 year period rehabbing and old
house.

With a prehung unit, remove the door and hinges. Take apart the
jambs. remove the stops. Rip the jamb right down the center (where
the stops will cover, then rip again to remove the inch (or
whatever). Your stop will cover the joint. You might want to
preinstall shims perfectly level, since it might be easiest to install
the frame in two parts. Not easy, no.

Why not use biscuit's and put the ripped jamb back together? That
would make it easier to install since it would now be one piece again.

I see I overlooked the 'prehung' bit. I didn't use them. I find that
a new door (no jambs) is much easier to do in that situation.

Yes, biscuits would work great if you have access to them. Also,
check with a custom jamb order. We used to get charged a measly 15
bucks a door for custom width jambs. Don't know if that would apply
to a 3 9/16" jamb or not.

I used my circular saw to rip it down on the side without the hardware. Didn’t have to take it apart, just had to remove one metal staple on both sides so you don’t damage your blade. The I took a hand plane to the cuts to make sure they were square. It will look a little thin on the outside but you will never notice.

Good day Bill!
It is quite simple. Mark the width you need directly on the jamb and cut the excess off. I prefer a circular saw, but a sharp jigsaw would work as well. You can make your cuts without disassembling the jamb or removing the door from the jamb. Just make sure you don't cut into your door:)

Bill asked his question in 2007. While I'm sure he would have appreciated
your suggestion, I'm afraid it's all for naught.

During the project, in an attempt to keep the dust contained, Bill closed the
existing door before he started cutting the jamb.

Unfortunately, Bill's saw was faulty and he was electrocuted when he plugged
it in. More unfortunately, since the door was closed, no one knew it and Bill
passed away.

On the bright side, since he hadn't cut the jamb yet, his wife was able to get a
full refund. While returning the door, she met a contractor who installed the
proper sized door - at a substantial discount. They dated (quietly) for about a
year and when they thought the time was right, they married. I hear he's done
a lot of work on the house since then and it apparently looks quite nice.
