Reaction Steps

75 g (0.308 mol) of 2-(2′-methylphenoxymethyl)-nitrobenzene (Example 11a) and 10 g of 5% Pt/C (platinum adsorbed on activated carbon) in 50 ml of methanol are stirred vigorously under a hydrogen blanket for 2 hours. A further 2 g of 5% Pt/C is added and the mixture is stirred overnight. The catalyst is filtered off and replaced by 10 g of fresh catalyst. The mixture is stirred overnight and suction filtered, and the filtrate is evaporated down under reduced pressure. The residue is purified by column chromatography with mixtures of hexane and ethyl acetate. There is obtained 61 g (0.286 mol=93%) of the title compound as a colorless solid.
