Procedure

A mixture of 7-[2-(N-tert-butoxycarbonyl-4-hydroxypiperidin-4-yl)ethoxy]-6-methoxy-4-(2,3-methylenedioxyanilino)quinazoline (0.067 g), trifluoroacetic acid (0.5 ml) and methylene chloride (3 ml) was stirred at ambient temperature for 1 hour. The solvent was evaporated and the residue was partitioned between methylene chloride and a saturated aqueous sodium bicarbonate solution. The organic phase was washed with brine, dried over magnesium sulphate and evaporated. There was thus obtained the title compound (0.015 g); NMR Spectrum: (DMSOd6 and CF3CO2D) 1.75 (m, 4H), 2.05 (t, 2H), 3.1 (m, 4H), 4.0 (s, 3H), 4.35 (t, 2H), 6.1 (s, 2H), 6.95 (m, 3H), 7.4 (s, 1H), 8.1 (s, 1H), 8.85 (s, 1H); Mass Spectrum: M+H+ 439.
