実験手順: To a mixture of 1-amino-1-cyclopropanemethanol hydrochloride (1.1 g), benzaldehyde (945 mg) and triethylamine (1.24 ml) in 1,2-dichloroethane (10 ml), sodium triacetoxyborohydride (5.66 g) was added with ice-cooling over 5 minutes. After being stirred at room temperature for 13 hours, the mixture was poured into aqueous sodium bicarbonate solution and stirred for several hours. The organic layer was separated, dried over magnesium sulfate and evaporated under reduced pressure to give 1-(N-benzylamino)-1-cyclopropanemethanol (641 mg). was added with ice- cooling over 5 minutes stirred for several hours The organic layer was separated dried over magnesium sulfate evaporated under reduced pressure
