Reaction Steps

2-Nitro-N-((3aR,4S,6aS)-2-(4-(trifluoromethyl)phenylsulfonyl)octahydrocyclopenta[c]pyrrol-4-yl)benzenesulfonamide (250 mg, 0.481 mmol) from Example 299 and dimethyl sulfate (0.138 mL, 1.444 mmol) were combined in N,N-dimethylformamide (3 mL) at 0° C. and 1,8-diazabicyclo[5.4.0]undec-7-ene (0.145 mL, 0.962 mmol) was added dropwise. The reaction mixture was stirred for 0.5 hours, water was added, and the precipitate was collected by filtration. The resultant crude material was purified using a 12 g silica gel cartridge eluting with a gradient of 0-60% ethyl acetate/hexane over 20 minutes to give the title compound: 1H NMR (500 MHz, pyridine-d5) δ ppm 8.15 (dd, J=12.1, 4.7, 3H), 7.94 (d, J=8.3, 2H), 7.88 (dd, J=7.7, 1.3, 1H), 7.68 (dtd, J=19.1, 7.5, 1.3, 2H), 4.29 (dt, J=10.8, 7.0, 1H), 3.63 (dd, J=9.9, 1.5, 1H), 3.21 (dd, J=9.7, 2.3, 1H), 2.90 (s, 3H), 2.89-2.81 (m, 2H), 2.58-2.39 (m, 2H), 1.83-1.72 (m, 1H), 1.68-1.58 (m, 1H), 1.50 (qd, J=11.8, 7.3, 1H), 1.21 (ddd, J=19.4, 12.4, 7.1, 1H); MS (ESI+) m/z 551 (M+NH4)+.
