ibuprofen is 4-isobutyl alpha-methyl phenylacetic acid. so i thought you could condense the ethyl ester with diethyl malonate or maybe even ethyl acetate and decarboxylate to get 4-isobutyl alpha-methyl p2p. a guy said that 4-isobutyl alpha-methyl amphetamine was "not bad", but i could use a little more feedback. any comments?
