실험 절차
Sodium borohydride (9.0 g, 0.34 mole) was added in portions to a stirred mixture of 55 g (0.24 mole) of methyl 5-(p-nitrophenyl)-2-furyl ketone in 700 ml of methanol at 20°-25° over 45 minutes. The mixture was stirred at ambient temperature for 4 hours and allowed to stand overnight. Some insoluble material was removed by filtration and discarded. The filtrate was poured into a mixture of ice and water (3 liters) and made acidific with 5% aqueous HCl. The brown oil which was deposited solidified on standing and was collected by filtration to give 56 g (100%) of title compound. Recrystallization from a cyclohexane-benzene mixture gave an analytical sample, m.p. 69.5°-70.5°.
