Procedure

Di-tert-butyl azodicarboxylate (0.208 g) was added dropwise to a stirred mixture of 4-(2-chloro-5-methoxyanilino)-5-hydroxy-7-methoxyquinazoline (0.2 g), 4-(3-hydroxypropyl)morpholine (Bull. Soc. Chim. Fr., 1962, 1117; 0.131 g), triphenylphosphine (0.237 g) and methylene chloride (3 ml). The reaction mixture was stirred at ambient temperature for 1 hour. The mixture was evaporated and the residue was purified by column chromatography on silica using a 99:1 mixture of methylene chloride and a saturated methanolic ammonia solution as eluent. The material so obtained was triturated under diethyl ether. The resultant solid was isolated, washed with diethyl ether and dried under vacuum to give the title compound (0.12 g); NMR Spectrum: (DMSOd6 and CF3COOD) 2.35 (m, 2H), 3.1 (t, 2H), 3.3 (t, 2H), 3.5 (d, 2H), 3.68 (t, 2H), 3.8 (s, 3H), 4.0 (d, 2H), 4.02 (s, 3H), 4.6 (t, 2H), 6.93 (s, 1H), 7.05–7.15 (m, 2H), 7.5 (s, 1H), 7.57 (d, 1H), 8.87 (s, 1H); Mass Spectrum: M+H+ 459 and 461; Elemental Analysis: Found C, 60.0; H, 6.0; N, 12.1; C23H27ClN4O4 requires C, 60.19; H, 5.93; N, 12.2%.
