Reaction Conditions

Reaction Steps

A mixture of 4-(1-methyl-1H-pyrazol-5-yl)phenol (500 mg), 2,2,2-trifluoroethyl trifluoromethanesulfonate (999 mg), potassium carbonate (793 g) and acetonitrile (5.0 mL) was stirred at 90° C. for 2 hours. Thereafter, the reaction solution was diluted with chloroform, and insoluble matters were then removed by filtration. The filtrate was concentrated under a reduced pressure, and the residue was then purified by column chromatography (silica gel 60N, chloroform:methanol=100:0 to 98:2), so as to obtain the title compound (485 mg) in the form of a light yellow solid.
