Participants

Reaction Steps

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.
