2,4-Dinitrobenzaldehyde → 2,4-Dinitrobenzenemethanol

Participants

Reaction Steps

Sodium borohydride (0.2 g, 10 mmol) in ethanol (40 ml) was added dropwise to 2,4-dinitrobenzaldehyde (1.96 g, 10 mmol) in ethanol (40 ml) and stirred for 1 h. The reaction mixture was then evaporated in vacuo, partitioned between ether and aqueous sodium bicarbonate, the ether layer dried (magnesium sulphate) and evaporated in vacuo to yield 2,4-dinitrobenzyl alcohol as a brown solid (1.147 g, 58%), m.p. 105°-110° C.;
