Procedure

This was prepared by the method described in example 4 using 4-chloro-6-methoxy-7-(3-morpholin-4-ylpropoxy)quinazoline (200 mg, 0.59 mmol), N′-[3-(7-amino-6-chloro-1,3-benzodioxol-4-yl)prop-2-yn-1-yl]-N,N-dimethylurea (193 mg, 0.65 mmol) and a solution of sodium bis(trimethylsilyl)amide (1.0M in THF, 1.24 ml) in DMF (3 ml). The crude product was purified by column chromatography on silica using 10% methanol in dichloromethane as eluent. There was thus obtained the title compound (254 mg, 72%) as a pale brown solid; NMR Spectrum:(DMSOd6) 1.96 (quintet, 2H), 2.39 (m, 4H), 2.45 (t, 2H), 3.81 (s, 6H), 3.60 (m, 4H), 3.94 (s, 3H), 4.10 (d, 2H), 4.20 (t, 2H), 6.15 (s, 2H), 6.84 (t, 1H), 7.08 (s, 1H), 7.20 (s, 1H), 7.82 (s, 1H), 8.34 (s, 1H), 9.50 (s, 1H); Mass Spectrum: M+H+ 597/599.
