Reaction Steps
Methanesulfonyloxy-(4-trifluoromethyl-phenyl)-acetic acid ethyl ester (I102) (594 mg, 1.82 mmol), aniline (0.25 mL, 2.73 mmol), and DIPEA (0.48 mL, 2.73 mmol) are dissolved in acetonitrile (4 mL). The reaction is heated under microwave irradiation at 100° C. for 1 hour and 30 minutes. Aniline (0.17 mL, 1.820 mmol) is added again and the reaction is heated under microwave irradiation at 100° C. for 3 hours. Acetonitrile is removed under vacuum and the residue is purified by flash chromatography (Petroleum ether/DCM=75/25) to afford intermediate I151 as a yellow oil (195 mg, 60% yield).
