実験手順

A mixture of 4-chloro-6-methoxy-7-(3-pyrrolidin-1-ylpropoxy)quinazoline (100 mg, 0.31 mmol), (prepared as described for the starting material in Example 9), and 7-hydroxy-2,4-dimethylquinoline (64 mg, 0.36 mmol), (Chem. Berichte, 1903, 36, 4016), in DMF (3 ml) containing potassium carbonate (86 mg, 0.62 mmol) was heated at 90° C. for 3 hours. After cooling, the mixture was poured onto a column of silica and eluted with 2.5M ammonia in methanol/methylene chloride (5/95) to give 4-(2,4-dimethylquinolin-7-yloxy)-6-methoxy-7-(3-pyrrolidin-1-ylpropoxy)quinazoline (50 mg, 35%).
