The resulting suspension was heated at 150° C. for 2 hours. The reaction mixture was diluted with EtOAc (60 mL), and washed sequentially with water (20 mL) and saturated brine (20 mL). The organic layer was dried over MgSO4, filtered and evaporated to afford N-adamantan-1-yl-6-chloro-2-(propylthio)nicotinamide (2.21 g, 100%) as a white solid.
