Procedure

(4-Benzyloxy-phenyl)-(6-chloro-pyrido[3,4-d]pyrimidin-4-yl)-amine (1.4 g) and 3-(1,3-dioxolan-2-yl)-phenyl-tributylstannane (3.08 g) [A. Lee and W-C. Dai, Tetrahedron (1997), 53(3), 859-868] in dioxan (30 ml) were reacted together as in Procedure B. The mixture was evaporated and the residue suspended in dichloromethane. This was then filtered through celite and the solvent evaporated. The gummy residue was then triturated with hexane giving a beige solid. This material was further purified by column chromatography, giving a brown foam (252 mg); m/z 477 (M+1)+.
