Procedure

26.6 g (0.0886 mol) of 3,5-dinitro-2-isopropylthiobenzoic acid methyl ester are dissolved in 270 ml of tetrahydrofuran and hydrogenated with the addition of 10 g of Raney nickel at from 30° to 35° C. The catalyst is then isolated by filtration, the filtrate is concentrated and the residue is crystallised from ethyl acetate/hexane.
