Reaction Steps

To N1-[(3aS,4R,6aR)-Octahydrocyclopenta[c]pyrrol-4-yl]-N2-(tert-butyloxycarbonyl)-N2-methyl-L-leucinamide from Step A (220 mg, 0.622 mmol) in dichloromethane (5.0 mL) was added triethylamine (0.130 mL, 0.934 mmol) followed by 3-(trifluoromethyl)benzene-1-sulfonyl chloride (0.110 mL, 0.685 mmol) and the reaction mixture was stirred at room temperature overnight. The reaction was reduced in volume and loaded onto a silica gel cartridge (Analogix®, Burlington, Wis., RS-24). The title compound was eluted with a gradient of 0% to 10% methanol (2 N ammonia)/dichloromethane over 20 minutes to give N2-(tert-butyloxycarbonyl)-N2-methyl-N1-((3aS,4R,6aR)-2-{[3-(trifluoromethyl)phenyl]sulfonyl}octahydrocyclopenta[c]pyrrol-4-yl)-L-leucinamide: 1H NMR (500 MHz, pyridine-d5) δ ppm 8.32 (bs, 1H), 8.18-8.13 (m, 1H), 8.02-7.95 (m, 1H), 7.90-7.84 (m, 1H), 7.68 (t, J=7.9, 1H), 4.17-4.09 (m, 1H), 3.77-3.69 (m, 1H), 3.20-3.11 (m, 2H), 3.05-2.97 (m, 4H), 2.53-2.47 (m, 2H), 1.98-1.88 (m, 1H), 1.87-1.71 (m, 3H), 1.62-1.48 (m, 3H), 1.46 (s, 9H), 1.32-1.22 (m, 1H), 0.87 (dd, J=6.6, 15.5, 6H).
