PVC isn't a good idea. It release some nasty ass shit when heated. I'm not sure if the temperatures in the nuker would be high enough to cause problems, but heating plastic pipe under pressure doesn't sound kosher. I'd use steel.
The amination ala Iudekx can be found on Rhodium's site, mmda.txt, under the heading "OTC MMDA from Parsely Oil" or something like that.
I don't understand why everyone here has so much trouble with microwave apparati. If you're gonna do some nuking in your dreams, make a reflux apparatus for your microwave. Despite popular belief, you don't need to cut holes in your nuker. Try this instead:
Locate the wave source in your microwave. Usually, the wave source is a 12" diameter disk seen in the top of the cooking chamber (in here is a big metal propeller than spins and help distribute waves). Now, there should be some room on either side of the disk (if not, you can use an area underneath it. Take a peice of metal with no holes larger than a few millimeters, and use to to block off a section of your microwave. The wave source should not be located inside this new chmaber, the shield must be between the walls of the nuker and the wave source. Now, grab a bukcet of ice, and stick it in the new chamber. For your reaction "Flask" get some microwave safe container, and rig it with some hose coming out of the top, and returning to the bottom. Place the flask in the main microwave chamber, with the hose running into your shielded chamber and through your bowl of ice. Voila, instant reflux condensor.
Alternatively, you can go here

and buy some nuker shieding instead of the metal shield. Both will block microwaves, but for the skeptics...
The ice will melt eventually, but the shielding will be sufficient to prevent that for long periods of time. Nothing says you can't pop open the microwave and put more ice in though, and a good supply of ice should last a while. Fiberglass insulation can be added to further buffer you ice chamber fomr the nasty nuker.
