34801-09-7, These common heterocyclic compound, 34801-09-7, name is N-(2-Aminophenyl)acetamide, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
A mixture of 1.00 g (5.2 mmol) of compound 1a and 0.78 g (5.2 mmol) of N-(2-amino-phenyl)acetamide in 10 mL of ethanol was refluxed for 1 h. The mixture was cooled and evaporated by half, and the yellow solid was filtered off. Yield 1.20 g (71%), mp 130-132C (decomp., from EtOH). IR spectrum, nu, cm -1 : 3272 (NH, OH), 1715 (C=O). 1 H NMR spectrum, delta, ppm: 2.11 s (3H, Me), 6.38 s (1H, 3-H), 7.07 m (1H, H arom ), 7.17 m (2H, H arom ), 7.32 m (1H, H arom ), 7.49-7.60 m (3H, H arom ), 7.96 m (2H, H arom ), 9.82 s (1H, NH), 11.61 s (1H, NH). 13 C NMR spectrum, delta C , ppm: 22.8 (Me), 95.3 (C 3 ); 122.6, 125.1, 125.9, 127.1, 128.2, 128.5, 128.9, 130.3, 131.9, 138.5 (C arom ); 151.9 (C 2 ), 165.2 (COOH), 168.8 (CONH), 189.3 (COPh).
