Reaction Steps
To a solution of 2-amino-4-methoxy benzoic acid (8.6 g, 51.4 mmol) in 2-dimethoxy ethane (100 ml) was added formamidine (10.71 g, 103 mmol). The reaction mass was heated to 125° C. 18 h. The reaction mass was diluted with cold water. The precipitated solid was filtered, washed with water to get crude compound (6.92 g, 74.8%) as pale yellow solid. 1H NMR (400 MHz, DMSO): δ ppm 12.10 (br, s, 1H), 8.06 (s, 1H), 8.03-8.01 (d, J=8 Hz, 1H), 7.11-7.09 (m, 2H), 3.89 (s, 3H);
