To a mixture of tetrakis(triphenylphosphine)palladium (188 mg, 163 μmol) and sodium methoxide (176 mg, 3251 μmol) was added a solution of 4-(7-bromo-1,5-naphthyridin-4-ylthio)benzenamine (540 mg, 1625 μmol) in DMF (2 mL). The resealable tube was purged with argon, and the mixture was heated to 100° for 1.5 h. The mix was diluted with ethyl acetate, washed with brine twice, dried with sodium sulfate, and concentrated. The residue was purified by silica gel chromatography using 1-10% MeOH:CH2Cl2 w/1% NH4OH to provide 4-(1,5-naphthyridin-4-ylthio)benzenamine. MS m/z=254 [M]+. Calc'd for C14H11N3S: 253.32.
