실험 절차

To a solution of 2-amino-4-chloro-5-nitrobenzamide (3.0 g, 13.7 mmol) in dry THF (50 mL), borane dimethyl sulphide complex (1.56 g, 20.6 mmol) was added at RT and the reaction mass was refluxed for 24 h. The reaction mass was cooled to RT and dilute HCl was added till it became acidic. Further, the reaction mixture was stirred for 1 h and then the reaction mixture was basified with dilute NaOH and extracted with ethyl acetate. The organic layer was separated, dried over anhydrous sodium sulphate and concentrated to afford 2.0 g of the desired product. 1H NMR (300 MHz, DMSO d6): δ 3.58 (s, 2H), 6.72 (br s, 3H), 8.04 (br s, 1H); MS (m/z): 200.28 (M−H).
