Versuchsvorschrift
Using an analogous procedure to that described in the preparation of the starting material in Example 8, 4-(4-bromo-2,6-difluoroanilino)-7-hydroxy-6-methoxyquinazoline (1 g, 2.62 mmol) was reacted with 1-(tert-butoxycarbonyl)-4-hydroxymethylpiperidine (845 mg, 3.93 mmol), (prepared as described for the starting material in Example 1), to give 4-(4-bromo-2,6-difluoroanilino)-7-(1-(tert-butoxycarbonyl)piperidin-4-ylmethoxy)-6-methoxyquinazoline (620 mg, 41%).
