Reaction Steps
To the DCM solution (10 ml) of 2-(1-benzofuran-2-yl-cyclopropyl)-4-methoxy-benzoic acid (1.0 g, 3.24 mmol), trifluoroacetic acid anhydride (0.45 ml, 3.24 mmol) was added at −78° C., and the mixture was stirred at −78° C. for 10 min, at −50° C. for 10 min, and at −30° C. for 20 min. Thereafter, the mixture was added with water and extracted with DCM. The residues obtained after concentration under reduced pressure were washed with DCM and hexane to obtain the title compound (0.163 g, 70%).
