Reaction Conditions

Reaction Steps

1500 ml of dry dimethylformamide (DMF) are placed in a 1000 ml four-necked flask while passing nitrogen over it and 72.67 g (0.6 mol) of 4-fluorocyanobenzene and 61.2 g (0.9 mol) of imidazole and finally 21.6 g (0.9 mol) of sodium hydride are added. The reaction mixture is heated to 100° C., stirred at this temperature for 4 hours and subsequently overnight at room temperature. The reaction mixture is then poured into water and the resulting mixture is extracted a number of times with dichloromethane. The organic phase is dried, evaporated on a rotary evaporator and finally dried further at 60° C. under reduced pressure. The yield is 94 g (93% of theory).
