Reaction Steps

To a solution of 5-(3-chloro-5-(trifluoromethyl)phenyl)-3-(4-(3-fluoroazetidin-3-yl)phenyl)-5-(trifluoromethyl)-4,5-dihydroisoxazole (Preparation 22, 95 mg, 0.2 mmol) in CH2Cl2 (5 mL) was added triethylamine (0.15 mL, 1.1 mmol) and DMAP (5 mg, 0.04 mmol). Contents were stirred for 30 minutes at which time mesyl chloride (25 mg, 0.2 mmol) was added and the reaction was stirred for 18 hours at room temperature. Next, the reaction was concentrated to ˜3 mL under nitrogen purge and injected directly onto a 24 g Redi-Sep column. The crude material was chromatographed eluting from 100% heptane to 30:70 EtOAc:heptane to afford the final product (95 mg, 94%) as a solid. 1HNMR (CDCl3) δ ppm: 7.85 (1H), 7.79-7.77 (3H), 7.72 (1H), 7.64 (2H), 4.50-4.42, (2H), 4.34-4.27 (2H), 4.18 (1H), 3.76 (1H), 3.03 (3H); m/z (Cl) 545 ([M+H]+.
