반응 단계

As described in Method A, N-(4-fluoro-phenyl)-6-mercapto-nicotinamide IIa (745 mg, 3 mmol, 1 eq.) and 2-bromomethyl-4-methoxyphenyl bromide (0.84 g, 3 mmol, 1 eq.) were suspended in ethanol (36 ml). To the suspension, 1 N sodium hydroxide (5.1 ml, 6 mmol, 2 eq.) was added, and the reaction mixture heated to gentle reflux for 2 hours, then water (200 ml) was added to the reaction mixture while still hot. Upon cooling, a white precipitate formed, and this was filtered, washed with 50% aqueous ethanol, then water and dried in the oven to afford 1.33 g (99% yield, >95% purity by LC-MS) of 6-(2-bromo-5-methoxy-benzylsulfanyl)-N-(4-fluoro-phenyl)-nicotinamide, intermediate VII, as an off-white solid. ESI-MS m/z=448.9 [M+H]+.
