Procedure
This was prepared using the method described in example 13 using N-[5-chloro-7-(4-methoxybut-1-yn-1-yl)-1,3-benzodioxol-4-yl]-7-(3-chloropropoxy)-6-methoxyquinazolin-4-amine (200 mg, 0.40 mmol) and 4-methoxypiperidine (246 mg, 2.14 mmol) in 2-methoxyethanol (4 ml). The crude product was purified by column chromatography on silica using increasing concentrations of methanolic ammonia in dichloromethane as eluent. There was thus obtained the title compound (184 mg, 80%) as a pale yellow solid; NMR Spectrum:(CDCl3) 1.55-1.70 (m, 2H), 1.85-2.00 (m, 2H), 2.10 (quintet, 2H), 2.24 (m, 2H), 2.56 (t, 2H), 2.72 (t, 2), 2.78 (m, 2H), 3.24 (m, 1H), 3.34 (s, 3H), 3.42 (s, 3H), 3.62 (t, 2H), 3.98 (s, 3H), 4.24 (t, 2H), 6.05 (s, 2H), 6.90 (s, 1H), 7.04 (s, 1H), 7.09 (s, 1H), 7.28 (s, 1H), 8.61 (s, 1H); Mass Spectrum: M+H+ 583/585.
