Reaction Steps
A solution of 3-cyclopentyl-2-(4-methanesulfonyl-3-trifluoromethyl-phenyl)-propionic acid (182 mg, 0.5 mmol) in methylene chloride (5.0 mL) was cooled to 0° C. and then treated with a 2.0M solution of oxalyl chloride in methylene chloride (0.28 mL, 0.56 mmol) and a few drops of N,N-dimethylformamide. The reaction mixture was stirred at 0° C. for 15 min and at 25° C. for 30 min. The reaction mixture was then treated with a solution of 2-aminoquinoline (153 mg, 1.06 mmol) in tetrahydrofuran (2 mL) and triethylamine (0.17 mL, 1.20 mmol). This solution was stirred at 25° C. for 50 h. At this time, the reaction was concentrated in vacuo. Biotage chromatography (FLASH 40S, Silica 70/30 hexanes/ethyl acetate) afforded 3-cyclopentyl-2-(4-methanesulfonyl-3-trifluoromethyl-phenyl)-N-quinolin-2-yl-propionamide (140.3 mg, 57.2%) as a pale yellow solid: mp 90-95° C.; EI-HRMS m/e calcd for C25H25F3N2O3S (M+) 490.1538, found 490.1532.
