Procedure

A solution of N-[(E)-5-hydroxy-2-adamantyl]-2-{4-[5-(trifluoromethyl)pyridin-2-yl]piperazin-1-yl}acetamide (66 mg, 0.15 mmoles) from Example 2 in DCM (0.5 mL) was cooled to −78° C., treated with (diethylamino)sulfur trifluoride (DAST) (0.020 mL, 0.16 mmoles) and slowly warmed to room temperature over 6 hours. The mixture was quenched with aqueous saturated sodium bicarbonate (0.1 mL), filtered through a Celite cartridge and purified (silica gel, 10-15% acetone in hexane) to provide the title compound as a white solid. 1H NMR (300 MHz, CDCl3) δ 8.42 (s, 1H), 7.63 (m, 2H), 6.68 (d, J=9.2 Hz, 1H), 4.09 (d, J=8.5 Hz, 1H), 3.69 (s, 4H), 3.09 (s, 2H), 2.69 (s, 4H), 2.27-2.22 (m, 3H), 2.06 (m, 2H), 1.94 (m, 4H), 1.58-1.54 (m, 4H); (APCI+) m/z 441 (M+H)+.
