Sodium hydride → HCID 42629463, compound

Participants

Reaction Steps

To a stirred solution of 1-(4-(trifluoromethyl)phenyl)piperidin-4-ol (1.4 g, 5.71 mmol) in dimethylformamide (10 mL) at room temperature was added sodium hydride slowly (0.5 g, 60%, 12.4 mmol). After effervescence subsided, tert-butyl 4-(6-chloropyridine-3-sulfonamido)piperidine-1-carboxylate (1.03 g, 4.75 mmol) was added slowly. The mixture was stirred at room temperature overnight and then poured into ice-water. The residue was purified by flash chromatography (silica gel, 2% methanol in methylene chloride) to afford the title compound as a yellow solid (2.75 g, 99%). 1H-NMR (CDCl3, 300 MHz): δ 8.64 (s, 1H), 7.97 (dd, 1H), 7.47 (d, 2H), 6.98 (d, 2H), 6.79 (d, 1H), 5.37 (m, 1H), 4.91 (d, 1H), 3.93 (m, 2H), 3.63 (m, 2H), 3.29 (m, 2H), 2.861 (m, 2H), 1.97 (m, 2H), 1.78 (m, 2H), 1.43 (s, 9H), 1.41 (m, 2H); LCMS: MS (m/z): 585 (MH+)
