実験手順

Diethyl azodicarboxylate (295 μl, 1.8 mmol) was added dropwise to a solution of 1-(3-hydroxypropyl)-[1,2,4]-triazole (119 mg, 0.93 mmol), (EP0060696 A1), 4-(4-chloro-2-fluoroanilino)-7-hydroxy-6-methoxyquinazoline (200 mg, 0.62 mmol), (prepared as described for the starting material in Example 24), and triphenylphosphine (492 g, 1.8 mmol) in methylene chloride (4 ml) and the mixture stirred for 3 hours at ambient temperature. The mixture was purified by column chromatography eluting with methylene chloride/acetonitrile/methanol (60/32/8). The purified product was triturated with a mixture of pentane and ether, collected by filtration and dried under vacuum to give a white solid. This solid was dissolved in methylene chloride/methanol and ethereal hydrogen chloride (1 ml of a 5M solution) was added. The volatiles were removed by evaporation. The solid residue was suspended in ether, collected by filtration, washed with ether and dried under vacuum to give 4-(4-chloro-2-fluoroanilino)-6-methoxy-7-(3-(1,2,4-triazol-1-yl)propoxy)quinazoline hydrochloride (121 mg, 39%). 1H NMR Spectrum: (DMSOd6; CF3COOD) 2.44(t, 2H); 4.0(s, 3H); 4.3(t, 2H); 4.5(t, 2H); 7.32(s, 1H); 7.47(dd, 1H); 7.62(t, 1H); 7.70(dd, 1H); 8.08(s, 1H); 8.41(s, 1H); 887(s,1H); 9.10(s, 1H) MS-ESI: 429 [MH]+
