실험 절차

Under ice cooling, 75.7 g of sodium borohydride is introduced within one hour into 128.0 g of 4-benzyloxy-3-nitrobenzaldehyde in 4.2 l of methanol. After 1.5 hours of agitation at room temperature, 1.1 l of 2N HCl is added dropwise. The isolated reaction product is recrystallized from a mixture of 680 ml of diisopropyl ether and 170 ml of isopropanol, thus obtaining 103.0 g of 4-benzyloxy-3-nitrobenzyl alcohol, mp 76°-77° C.
