70% | In tetrahydrofuran; at 0 - 20℃; for 12h; | At 0 C,To 4-tert-butylbenzene-1,2-diamine (I-9, 5.02 g, 30.5 mmol)Add in tetrahydrofuran (400mL) solution1,1'-carbonyldiimidazole (CDI, 5.43 g, 33.6 mmol),The resulting solution was stirred at room temperature for 12 hours.Then diluted with diisopropyl ether (50 mL),The mixture was stirred for a further 30 minutes at room temperature.White precipitates gradually appear,Filter and collect products,Wash with diisopropyl ether (50 mL),Vacuum drying,4.05 g (yield: 70%) of 5-tert-butyl-1H-benzo[d]imidazole-2(3H)-one (IX-1),It is a white solid. |
In tetrahydrofuran; dichloromethane; at 20℃; for 6.5h; | General procedure: To a solution of 4-methyl-1,2-phenylenediamine (25 g, 0.205 mol) in tetrahydrofuran (375 mL) was added dropwise a solution of 1,1'-carbonyldiimidazole (36.5 g, 0.225 mol) in dichloromethane (375 mL). After stirring for 6.5 h at ambient temperature, to the reaction mixture was added diisopropyl ether (375 mL). After stirring at ambient temperature, the resulting precipitates were collected by filtration. The precipitates were washed with diisopropyl ether and dried in vacuo to give 5-methyl-1,3-dihydrobenzimidazol-2-one (24.6 g, 70.1%). |
