Procedure

A solution of 3-methylene-1-methylcyclopentanecarboxylic acid, (600 mg, 4.28 mmol) 3,5-bis(trifluoromethyl)benzylamine hydrochloride (1.196 g, 4.28 mmol), 1-hydroxy-7-azabenzotriazole (583 mg, 4.28 mmol) and diisopropylethylamine (745 μL, 4.28 mmol) and 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (EDC, 1.230 g, 0.168, 6.42 mmol) in dichloromethane (10 mL) was stirred at room temperature for 1 hr. The reaction mixture was diluted with dichloromethane (40 mL) and washed with water (3×30 mL), brine (1×30 mL), dried (anhydrous sodium sulfate) and the solvent was evaporated under reduced pressure. The crude product was purified via mplc (Lobar Fertigsaule, LiChroprep, 40-63 μm, ethyl acetate/hexanes (1:4)) yielding 777.6 mg (49%) of pure product. 1H NMR (500 MHz, CDCl3) 7.79 (s, 1H), 7.70 (s, 2H), 6.19 (bs, 1H), 4.98 (bs, 1H), 4.92 (bs, 1H), 4.62 (dd, 15.6 Hz, 6.2 Hz, 1H), 4.54 (dd, 15.8 Hz, 6.0 Hz, 1H), 2.78 (bd, 15.8 Hz, 1H), 2.46 (m, 2H), 2.30 (bd, 15.8 Hz, 1H), 2.18 (m, 1H), 1.70 (m, 1H), 1.31 (s, 3H).
