1-(p-Methoxyphenyl)-2-propanone → HCID 18352986, compound

Participants

Reaction Steps

A solution of sodium cyanoborohydride (1.07 grams, 17 mmole), 4-aminomethyl-1-(tert-butoxycarbonyl)piperidine (3.0 grams, 14.3 mole) and 1-(4-methoxyphenyl)propan-2-one (2.35 grams, 14.31 mmole) in methanol (50 ml) was stirred at 22° C. for 17 hours. The mixture was concentrated under reduced pressure and the residue was partitioned between ethyl acetate and water. The dried (anhydrous magnesium sulfate) organic phase was concentrated under reduced pressure to leave N-[2-(4-methoxyphenyl)-1-methylethyl]-[1-(tert-butoxycarbonyl)piperidin-4-ylmethyl]amine as an oil (4.28 grams, 82%); hydrochloride, m.p. 198-199° C. (methanol/ethyl ether), M+H 391.
