Controller:

[HttpPatch("{id:int}")]
        public async Task<ActionResult> Patch([FromRoute] int id, [FromBody] JsonPatchDocument<ProductoPatchDTO> patchDocument)
        {
            if (patchDocument == null) { return BadRequest(); }

            var productoBD = await this._context.Producto
                .Include(prodFarm => prodFarm.Farmacias)
                .FirstOrDefaultAsync(prod => prod.Id == id);

            if (productoBD == null) { return NotFound(); }

            var productoDTO = this._mapper.Map<ProductoPatchDTO>(productoBD);
            patchDocument.ApplyTo(productoDTO, ModelState);

            var valido = TryValidateModel(productoDTO);
            if (!valido) { return BadRequest(ModelState); }

            this._mapper.Map(productoDTO, productoBD);

            await this._context.SaveChangesAsync();

            return NoContent();
        }

MapperProfile.cs

 public MapperProfile()
        {
            // Controller Producto
            CreateMap<Producto, ProductoDTO>();
            CreateMap<ProductoCreacionDTO, Producto>()
                .ForMember(x => x.Farmacias, opciones => opciones.MapFrom(MapCrearProductoConFarmacia));
            CreateMap<ProductoPatchDTO, Producto>().ReverseMap();
            CreateMap<ProductoFarmaciaPatchDTO, ProductoFarmacia>().ReverseMap();
        }
