YieldReaction ConditionsOperation in experiment
37% With sodium dithionite In ethanol; water at 70℃; for 2 h; A mixture of 4-amino-3-methyl-5-nitrobenzoic acid (0.98 g, 5 mmol, 1 eq.), sodium dithionite (2.47 g, 14 mmol, 2.8 eq.), /7-butyraldehyde (0.38 g, 5 mmol, 1.0 eq.), ethanol (15 mL) and water (15 mL) was heated to 70 0C for 2 h. The reaction mixture was cooled to room temperature and ethanol was removed by rotary evaporator. The solid precipitated was washed with water, collected by filtration and dried under vacuum to give an off-white solid. Yield: 0.41 g (37percent).1H NMR (400 MHz, DMSO-ofe): δ 12.42 (s. 1 H), 7.82 (s, 1 H), 7,56 (s, I H), 2.80 (t, J= 7 A Hz, 2H), 2.50 (s, 3H), 1.79 (qd, J= 7.4 Hz, J= 7.32 Hz, 2H), 0.94 (t, J= 7.32 Hz, 3H). "C NMR (100 MHz, DMSO-αfc): δ 168.6, 157.5, 124.1 , 123.3, 31.0, 21.4, 17.1 , 14.2.
