Procedure
A mixture of 4-(2,4-dichloro-5-methoxyanilino)-7-[3-(4-tert-butoxycarbonylpiperazin-1-yl)propoxy]-5-tetrahydropyran-4-yloxyquinazoline (0.12 g) and trifluoroacetic acid (2 ml) was stirred at ambient temperature for 2 hours. The mixture was evaporated and the residue was triturated under diethyl ether. The resultant solid was isolated and dried under vacuum. The solid was dissolved in diethyl ether and 6M hydrogen chloride gas in diethyl ether (0.5 ml) was added. The resultant solid was isolated, washed with diethyl ether and dried under vacuum. There was thus obtained the title compound (0.112 g); NMR Spectrum: (DMSOd6 and CF3CO2H) 1.9–2.1 (m, 2H), 2.15 (d, 2H), 2.28–2.4 (m, 2H), 3.4 (m, 2H), 3.4–3.9 (m, 10H), 3.92 (s, 3H), 3.95 (m, 2H), 4.39 (t, 2H), 5.2 (m, 1H), 7.0 (d, 1H), 7.2 (d, 1H), 7.78 (s, 1H), 7.82 (s, 1H), 8.9 (s, 1H); Mass Spectrum: M+H+ 562 and 564.
