Conditions

Temperature: 100 °C

Procedure

4-Chloro-N-(4-(7-methoxy-1,5-naphthyridin-4-ylthio)phenyl)phthalazin-1-amine (148 mg, 331 μmol), 1-methyl-4-(trimethylstannyl)pyridin-2(1H)-one (90 mg, 331 μmol), and the Pd catalyst were added to toluene and heated to 100° C. for 2 h. The mixture was concentrated and purified by silica gel chromatography using 0 to 30% MeOH in ethyl acetate. MS: M+H+=519.
