実験手順
1,1′-(Azodicarbony)dipiperidine (1.56 g, 6.2 mmol) followed by 3-(methylthio)-1-propanol (0.32 ml, 3 mmol) was added to a mixture of 4-(4-bromo-2-fluoroanilino)-7-hydroxy-6-methoxyquinazoline (225 mg, 7.0 mmol), (prepared as described for the starting material in Example 48), and tributylphosphine (1.42 mL 6.1 mmol) in methylene chloride (20 ml) at 5° C. The mixture was stirred at 5° C. for 1 hour and then for 18 hours at ambient temperature. The insolubles were removed by filtration and the volatiles were removed from the filtrate by evaporation. The residue was purified by column chromatography eluting with ethyl acetate/methanol (100/0 increasing to 95/5) to give 4-(4-bromo-2-fluoroanilino)-6-methoxy-7-(3-methylthiopropoxy)quinazoline (400 mg, 50%).
