Reaction Steps

The solution of 1.70 g (9.0 mmol) of 4-(ethoxycarbonylamino-methyl)-piperidine (obtained from 4-aminomethyl-piperidine and diethyl carbonate in the presence of 4-dimethylaminopyridine) in 18 ml of methanol was treated with 9.0 ml (9.0 mmol) of 1N methanolic hydrochloric acid. After addition of 0.53 g (3.0 mmol) of 8-methoxy-2-tetralone, the mixture was stirred for a further 5 minutes. 0.20 g (3.3 mmol) of sodium cyanoborohydride was then added and the mixture was stirred for 15 hours at room temperature, followed by standing for 18 days at about +4° C.
