Reaction Conditions

Reaction Steps

A suspension of Intermediate 7 (0.1 g, 0.405 mmol) and 4-(trifluoromethyl)aniline (ALDRICH, 0.051 mL, 0.405 mmol) in ethanol (5 mL) was heated at 50° C. for 1 h. The reaction mixture was concentrated under vacuum, redissolved in DCM (20 mL) and washed with aq. Na2CO3 (2×15 mL). The organic layer was dried over anhydrous Na2SO4, filtered and concentrated under vacuum to afford a white solid.
