A mixture of methyl 2-nitro-4-(trifluoromethyl)benzoate (2.49 g 0.01 mol), sodium hydrosulfite (8.71 g, 0.05 mol), ethanol (20 ml) and water (20 ml) was heated at 50° C. for 3 h. Water was added and extracted with ethyl acetate. The extracts were washed with water, dried over magnesium sulfate and concentrated in vacuo.
