実験手順: To a solution of piperazine (6 g, 69.77 mmol, 1.00 equiv) in acetonitrile (150 mL) was added potassium carbonate (19.2 g, 139.13 mmol, 2.00 equiv) and the mixture was stirred. To this was added dropwise a solution of 2-bromoacetonitrile (16.7 g, 140.34 mmol, 2.00 equiv) in acetonitrile (100 mL) and the suspension was stirred for 4 h at room temperature. The solids were Filtered out and the resulting solution was concentrated under vacuum. The crude product was purified by re-crystallization from methanol resulting in 7.75 g (68%) of Intermediate 50.1 as a white solid. the suspension was stirred for 4 h at room temperature The solids were Filtered out the resulting solution was concentrated under vacuum The crude product was purified by re-crystallization from methanol resulting in 7.75 g (68%) of Intermediate 50.1 as a white solid
