Reaction Steps

A screw capped vial was charged with 2-methoxy-4-(trifluoromethyl)phenyl boronic acid (0.096 g, 0.438 mmol), 7-(benzylthio)-4-bromo-1,6-naphthyridine (0.145 g, 0.438 mmol), and potassium phosphate tribasic (0.279 ml, 1.313 mmol). Dioxane (1.756 ml) and water (0.585 ml) were added and the vial was purged with argon, followed by addition of Pd(AmPhos)2Cl2 (0.019 g, 0.026 mmol). The vial was capped and heated to 110° C. After 3 hours, the reaction was cooled to room temperature, diluted with water (30 mL), and washed with ethyl acetate (20 mL×3). The organic layers were combined, dried over magnesium sulfate, filtered and concentrated. The resulting material was purified via silica gel MPLC chromatography (40 g), eluting with 0 to 100% ethyl acetate in heptanes. The fractions were collected and the solvent was removed under reduced pressure to provide 0.129 g of 7-(benzylthio)-4-(2-methoxy-4-(trifluoromethyl)phenyl)-1,6-naphthyridine as an off white solid. m/z (ESI) 427.2 (M+H)+.
