2-Acetamido-4-chloromethylthiazole → 7-((2-Acetamidothiazol-4-yl)methoxy)4-(2-fluoro-5-hydroxy-4-methylanilino)-6-methoxyquinazoline

Participants

Reaction Steps

Using an analogous procedure to that described in Example 27, 4-(2-fluoro-5-methoxycarbonyloxy-4-methylanilino)-7-hydroxy-6-methoxyquinazoline hydrochloride (470 mg 1.14 mmol), (prepared as described for the starting material in Example 22), and 2-acetamido-4-chloromethylthiazole (381 mg, 1.68 mmol) were combined to give 7-((2-acetamidothiazol-4-yl)methoxy)-4-(2-fluoro-5-hydroxy-4-methylanilino)-6-methoxyquinazoline (135 mg, 25%). 1H NMR Spectrum: (DMSOd6; CF3COOD) 2.16(s, 3H); 2.19(s, 3H); 4.00(s, 3H); 5.33(s, 2H); 6.91(d, 1H); 7.12(d, 1H); 7.33(s, 1H); 7.49(s, 1H); 8.16(s, 1H); 8.82(s, 1H) MS-ESI: 470 [MH]+
