Procedure
To a solution of N-(4-chloro-3-nitrobenzyl)-2,2,2-trifluoroacetamide (0.800 g) in methanol (20 mL) was added conc. HCl (2.0 ml). The reaction mass was refluxed for 18 h. Excess solvent was removed under vacuum to afford 0.700 g of desired product. 1H NMR (300 MHz, DMSO d6): δ 7.18 (s, 1H), 7.35 (s, 1H), 7.52 (s, 1H), 7.86 (s, 2H), 8.28 (s, 1H), 8.72 (br s, 2H).
