Rusted/partially broken drain pipe threads

The bathroom sink was clogged. Removed the U-shaped trap and the 90 degree elbow. The pipe that goes into the wall was clogged. When re-assembling the parts I noticed that the threads on the this pipe are severely corroded and uneven (part of the threads have broken off). I can't get the elbow to thread back on securely. How do I repair the damaged pipe (there appears to be about 3/4" of usable thread left on the pipe).
Thank you.
Thank you.

yes
I was concerned that I would cause more problems by taking that off.
I went with a temporary fix that uses a rubber coupling: it fits over both pieces and provides a tight seal (at least for right now). And it keeps the same geometry and dimensions.
There is a piece surrounding the pipe as it goes into the wall, looks like a donut. It could just be covering the hole but I don't know its function. That piece is not used in the other bathroom and you clearly see the hole in the wall.

The donut is called the esceution (sp?) plate, is is a finish plate to make the wall look nice by covering up the hole. In regards to your problem, the coupling that you used should be fine but I would take a close look at the other end of that rusted thru pipe. Often when one end of a threaded pipe is rusted out then the other end is not far behind.
When in doubt, tear it out.
