Participants

Reaction Steps

To a solution of N-cyclopropyl-N-piperidin-4-yl-3-trifluoromethyl-benzenesulfonamide (150 mg, 0.43 mmol) and pyridine-3-carboxaldehyde (46 mg, 0.43 mmol) in dichloroethane was added sodium triacetoxyborohydride (128 mg, 0.60 mmol, 1.4 eq.). The reaction mixture was stirred at room temperature for 12 hours. After this period, the solution was decanted and purified by flash chromatography to give the title compound 19 as a yellow oil. 1H NMR (CDCl3): δ 8.55-8.48 (m, 2H), 8.15-8.11 (m, 1H), 8.08-8.02 (m, 1H), 7.87-7.81 (m, 1H), 7.71-7.59 (m, 1H), 7.25-7.20 (m, 1H), 3.92-3.81 (m, 1H), 3.48 (s, 2H), 2.91-2.81 (m, 2H), 2.10-1.87 (m, 5H), 1.56-1.45 (m, 2H), 1.01-0.94 (m, m, 2H), 0.82-0.74 (m, 2H). LC: 100%. MS (EI): m/z 440 (M+H+).
