Reaction Steps

A mixture of 7-benzyloxy-4-(2-chloro-5-methoxyanilino)-5-(3-morpholinopropoxy)quinazoline (0.185 g), 10% palladium on charcoal catalyst (0.018 g), ethanol (2.5 ml), THF (2.5 ml) and DMF (1 ml) was stirred under an atmosphere pressure of hydrogen for 16 hours. The mixture was filtered and the filtrate was evaporated. The residue was purified by column chromatography on silica using a 9:1 mixture of methylene chloride and a saturated methanolic ammonia solution as eluent. There was thus obtained the title compound (0.045 g); NMR Spectrum: (DMSOd6) 2.05 (m, 2H), 2.35 (br s, 4H), 2.45 (t, 2H), 3.55 (t, 4H), 3.8 (s, 3H), 4.42 (t, 2H), 6.7 (d, 2H), 7.45 (d, 1H), 8.3 (s, 1H), 8.45 (s, 1H), 10.05 (s, 1H); Mass Spectrum: M+H+ 445.
