       Phenylpropanolamine Source?     

The only viable source of phenylpropanolamine I was aware of was otc pill extraction, but all of these drugs have vanished fromt he shelves and the only ones I am aware of which are still for sale are special pet medications which require a prescription.  Is anyone aware of another source or of a posible synthesis route?

       What's the wrong with you?     

What's the wrong with you? Don't you ever take advantage of TFSE, altavista/google or rhodium.ws?

Benzaldehyde+nitroethane+triethylamine to the nitroethene,
then reducting to the alcohol with Zn/formic, for example.

Benzaldehyde+nitroethane+triethylamine to the nitroethene
To much THC there eh? wink I think you meant :"to the nitroalcohol"

Follow this (../rhodium /para-fluoro-4-mar.html) procedure and omit the last two steps to get your PPA. Use regular benzaldehyde instead of the fluoroinated version of course!
