Sodium hydride (79 mg, 50% dispersion in mineral oil, 1.65 mmol) was added to a solution of N-(6-chloropyrid-3-yl)-N-methyl-methanesulphonamide (0.33 g) and 4-(3-mercaptophenyl)-4-methoxytetrahydropyran (0.34 g) in DMF (10 ml). The mixture was stirred at ambient temperature for 15 minutes and heated at 140° C. for 1.5 hours. After cooling, it was partitioned between water (75 ml) and ethyl acetate (75 ml). The organic phase was washed with brine (50 ml), dried (MgSO4) and the solvent evaporated. The product was purified by column chromatography to give N-(6-[3-(4-methoxytetrahydropyran-4-yl)phenylthio]pyrid-3-yl}-N-methylmethanesulphonamide as a gum (0.25 g, 41%).
