I seem to have found a cheap/easy solution at Lowes. The ID of the
iron pipe is about 3 3/4" Picked up a Fernco 3" to 3" donut, a section
of 3" PVC and a 1 1/2" to 3" PVC wye. Cut about an 8" section of 3"
pipe and put the donut on so about 2" of pipe is below the donut. This
fits VERY tightly into the pipe - maybe too tight. Put the wye above
the donut - the wider bell keeps the donut from sliding up. Managed to
push about 1/4 inch into the iron pipe and gave it a full garden hose
of water - No leaking through the donut (didn't seal the PVC yet).
Disassembled for the moment since I'm not ready to run the rest of the
pipe yet. I'll wire brush the ID of the iron to clean it up and help
push the donut down. Cleanout cap will go in the top of the wye, sink
drain into the side.

After cleaning lube the pipe and the donut with liquid dish soap. You can
do the same for the pvc. Sometimes this makes all the difference. Do not
substitute petroleum products.
