Participants

Reaction Steps

150 mg (0.434 mmol) of N-cyclopropyl-N-piperidin-4-yl-3-trifluoromethylbenzenesulfonamide (available from Lancaster) and 108 mg (0.434 mmol) of 4-butoxyphenylsulfonyl chloride (available from Matrix Scientific) were each dissolved in 10 mL of DCM and then combined. 1.5 eq. of DIEA (0.113 mL) was added to the mixture by syringe. The mixture was stirred overnight at room temperature and then concentrated under vacuum. The resultant product 29 was purified through a column of silica gel with a gradient of 0% to 20% EtOAc in hexanes and the pure material was concentrated (yield 25%, white solid). 1H NMR (CDCl3): δ 8.058 (s, 1H), 8.003-7.983 (d, 1H), 7.851-7.831 (d, 1H), 7.688-7.641 (m, 3H), 7.017-6.980 (m, 2H), 4.055-4.022 (t, 2H), 3.843-3.746 (m, 3H), 2.286-2.226 (t, 2H), 2.068-1.901 (m, 3H), 1.843-1.773 (m, 2H), 1.6151-1.470 (m, 4H), 1.014-0.976 (t, 3H), 0.944-0.903 (m, 2H), 0.793-0.744 (m, 2H). LC: 100%. MS (e/z): 562 (M+H+).
