Reaction Steps

A solution of 4-amino-6-methoxy-7-(1-methylpiperidin-4-ylmethoxy)quinazoline (150 mg) in DMF (4.5 ml) was added to sodium hydride (60% dispersion in mineral oil, 0.03 g) and the reaction mixture was stirred at ambient temperature for 20 minutes. 2,6-Dimethylphenyl isothiocyanate (0.162 g) was added and the mixture was stirred at ambient temperature for 20 hours. The reaction mixture was evaporated and the residual solid-was purified by column chromatography on silica using increasingly polar mixtures of methylene chloride and a 2M solution of ammonia in methanol as eluent. There was thus obtained the title compound (0.112 g); NM Spectrum: (CDCl3) 1.44-1.61 (m, 2H), 1.87-2.08 (m, 5H), 2.32 (s, 3H), 2.36 (s, 6H), 2.94 (d, 2H), 4.04 (m, 5H), 7.1 (s, 1H), 7.19 (m, 3H), 7.29 (s, 1H), 8.69 (s, 1H), 8.9 (s, 1H), 13.37 (s, 1H); Mass Spectrum: M+H+ 466.
