反応条件

実験手順

33.8 g of pentafluoropyridine (0.2 mol) are dissolved in 500 ml of dimethylformamide, the solution is cooled to 0° C. by means of a cryostat, and a solution of 53.3 g of potassium 4-benzyloxycarbonylphenoxide (0.2 mol) in 400 ml of dimethylformamide is then added drop wise over the course of 2 hours. After 24 hours at 0° C., the potassium salt has reacted.
