Participants

Reaction Steps

1 g (6.2 mmol) of commercially available (S)-3-phenylpiperidine was dissolved in dichloromethane and 0.37 ml acetic acid (6.51 mmol). After addition of 0.5 ml of propanal (6.93 mmol) and 1.97 g of sodium triacetoxyborohydride (9.3 mmol), the reaction mixture was stirred at room temperature for 18 h. Water was added, the layers separated, and the aqueous phase extracted with dichloromethane. The combined organic layers were dried over magnesium sulfate, filtered, and evaporated to dryness to yield 1.1 g of (S)-3-phenyl-1-propyl-piperidine.
