실험 절차
Put 8.00 g (45.13 mmol) 1-[benzyl(methyl)amino]acetone in 40 ml methanol. Add, at RT in portions with stirring, 854 mg (22.57 mmol) sodium borohydride. Stir for 30 min at RT and then for a further 30 min under reflux. Concentrate by evaporation and take up the residue in water. Extract twice with ethyl acetate, wash the combined organic phases once with satd. sodium hydrogencarbonate solution, dry over magnesium sulphate and concentrate by evaporation. 7.80 g (81.9% of theor.) of the target compound is obtained without further purification.
