Reaction Steps
To a solution of 4-chloro-3-(trifluoromethyl) aniline (3a) (0.5 g, 2.55 mmol) in dry THF (8 mL), cooled to 0° C., Et3N (0.4 mL, 2.76 mmol) followed by PivCl (0.34 mL, 2.8 mmol) were added. The reaction mixture was stirred at room temperature for 4 h. After completion of reaction (by TLC), the reaction mixture was diluted with water (20 mL) and extracted with EtOAc (3×15 mL). The combined organic extracts were washed with water (30 mL). The organic layer was separated dried over Na2SO4 and concentrated under reduced pressure to give the crude material which was triturated with n-hexane to afford the desired amide 3b (0.45 g, 60%) as a white solid.
