실험 절차

30.47 ml (30.47 mmol) of 1 M borane-THF complex solution are slowly added dropwise to a solution of 3.6 g (15.24 mmol) of [4-(tert-butoxycarbonyl)phenyl]acetic acid in 100 ml of THF at −10° C. with exclusion of oxygen. The mixture is stirred at 0° C. for 4 hours. Subsequently, ammonium chloride solution is added and the mixture is extracted with diethyl ether. The combined organic phases are washed with sodium chloride solution, dried over sodium sulphate and evaporated. 3.2 g (14.4 mmol, 92% yield) of the title compound are obtained.
