Reaction Steps

Using an analogous procedure to that described in Example 70, 7-benzyloxy-4-chloroquinazoline hydrochloride (307 mg, 1 mmol), (prepared as described for the starting material in Example 70), was treated with 4-chloro-2-fluoro-5-hydroxyaniline (193 mg, 1.2 mmol), (EP 061741 A2), to give 7-benzyloxy-4-(4-chloro-2-fluoro-5-hydroxyanilino)quinazoline hydrochloride (407 mg, 94%). m.p. 253-257° C. 1H NMR Spectrum: (DMSOd6) 5.37(s, 2H); 7.16(d, 1H); 7.32-7.5(m, 4H); 7.54(s, 1H); 7.56(d, 2H); 7.59(dd, 1H); 8.73(d, 1H); 8.86(s, 1H); 10.63(br s, 1H); 11.6(br s, 1H) MS-ESI: 396 [MH]+
