実験手順

To a solution of 4-chloro-6-methoxy-7-((1-(2-methylsulphonylethyl)piperidin-4-yl)methoxy)quinazoline (115 mg, 0.28 mmol) and 7-hydroxyquinoline (50 mg, 0.33 mmol) in DMF (1.5 ml) was added potassium carbonate (60 mg, 0.42 mmol). The mixture was stirred for 2 hours at 100° C. After cooling, and removal of the volatiles by evaporation, the residue was partitioned between ethyl acetate and water. The organic layer was washed with water, brine, dried (MgSO4) and evaporated. The residue was purified by column chromatography eluting with ethylacetate/methylene chloride/methanol (1/1/0 followed by 40/50/10 and 0/9/1). After removal of the volatiles by evaporation, the residue was triturated with pentane, filtered and dried under vacuum to give 6-methoxy-7-((1-(2-methylsulphonylethyl)piperidin-4-yl)methoxy)-4-(quinolin-7-yloxy)quinazoline (110 mg, 76%).
