Reaction Conditions

Reaction Steps

2.18 ml (12.9 mmol) of trifluoromethanesulphonic anhydride are slowly added dropwise to a solution, cooled to −10° C., of 1.54 g (8.6 mmol) of 3-(4-morpholinyl)-phenol and 3.59 ml (25.8 mmol) of triethylamine in 10 ml of dichloromethane. The mixture is stirred at −10° C. for 30 min and then at 0° C. for 30 min. It is washed successively with 10% strength sodium bicarbonate solution, water and saturated sodium chloride solution, dried over sodium sulphate and concentrated in vacuo, and the residue is dried under high vacuum. 2.41 g (90.1% of theory) of the title compound are obtained.
