YieldReaction ConditionsOperation in experiment
94% In toluene; at 100℃; for 3h; (c) Preparation of intermediary compound 2-[(4-Methylcarbamoyl-phenylamino)- methylenejmalonic acid diethyl ester:To a solution of 4-amino-iV-methyl-benzamide (7.5 g, 50 mmol) in anhydrous toluene (15 mL) was added diethoxymethylene malonate (11.88 g, 55.0 mmol) at room temperature. The reaction mixture was stirred at 100 0C for 3 hours, cooled to 40 0C and petroleum ether (200 mL) was added and the reaction mixture was subsequently stirred for 30 minutes. The solid formed, was collected by filtration, washed with diisopropylether and dried in vacuo to afford 15.0 g (94 % yield) of 2-[(4-methylcarbamoylphenylamino)methylene]malonic acid diethyl ester as a white solid. 1H-NMR (300 MHz, CDCl3) delta 11.09 (d, J= 13.5 Hz, IH), 8.54 (d, J= 13.5 Hz, 2H), 7.81 (d, J= 8.4 Hz, 2H), 7.18 (d, J= 8.7 Hz, 2H), 6.20 (bs, IH), 4.36-4.24 (m, 4H), 3.03 (d, J= 4.8 Hz, 3H), 1.41-1.33 (m, 6H). LC-MS (m/z, 0A): 319.6 (M-I, 99.7).
