反应详情

For example, a mixture of 6-chloro-2-(2-difluoromethylbenzimidazol-1-yl)-4-morpholino-1,3,5-triazine (3.66 g, 10 mmol), piperazine (3.45 g, 40 mmol), and acetone (50 ml) was stirred at room temperature for 16 hours. The reaction mixture was poured into water, and precipitated crystals were filtered, and washed with methanol to afford 2-(2-difluoromethylbenzimidazol-1-yl)-4-morpholino-6-(piperazin-1-yl)-1,3,5-triazine (3.87 g, 9.3 mmol) in a yield of 93% as colorless crystals.
