Versuchsvorschrift

To a solution of 4-[(4-fluoro-2-methyl-1H-indol-5-yl)oxy]-6-methoxyquinazolin-7-ol (2.5 g) in 1-methyl-2-pyrrolidinone (25 ml) and methyl tert-butyl ether (1.8 ml) was added potassium carbonate (815 mg). The mixture was degassed by holding under vacuum and letting down with nitrogen. This was carried out five times. The mixture was heated to 80° C. and 4-azoniaspiro[3,4]octane bromide (1.75 g) was added. The mixture was maintained at 80° C. for 3.5 hours. To the hot mixture was added water (27 ml) over 2 hours. The mixture was cooled to 64° C. and the solid filtered. The solid was washed with 1:1 v/v 1-methyl-2-pyrrolidinone/water (5 ml) and then water (4×5 ml). The solid was dried in a vacuum oven to give 4-[(4-fluoro-2-methyl-1H-indol-5-yl)oxy]-6-methoxy-7-(3-pyrrolidin-1-ylpropoxy)quinazoline.
