Procedure

This was prepared by the method described in example 4 but using 1-{3-[(4-chloro-6-methoxyquinazolin-7-yl)oxy]propyl}-4-methylpiperazin-2-one (140 mg, 0.38 mmol), 5-chloro-7-(4-methoxybut-1-yn-1-yl)-1,3-benzodioxol-4-amine (107 mg, 0.42 mmol) and sodium bis(trimethylsilyl)amide (1.0M in THF, 0.81 ml) in DMF (2 ml). The crude product was purified by column chromatography on silica using increasing concentrations of methanol in dichloromethane as eluent. There was thus obtained the title compound (150 mg, 67%) as a pale orange solid; NMR Spectrum:(DMSOd6) 2.04 (quintet, 2H), 2.20 (s, 3H), 2.59 (t, 2H), 2.72 (t, 2H), 2.91 (s, 2H), 3.30 (s, 3H), 3.32 (t, 2H), 3.47 (t, 2H), 3.53 (t, 2H), 3.94 (s, 3H), 4.14 (t, 2H), 6.14 (s, 2H), 7.07 (s, 1H), 7.15 (s, 1H), 7.83 (s, 1H), 8.32 (s, 1H), 9.49 (s, 1H);
