Procedure

The title compound was prepared from 2-amino-7-(4-fluoro-2-pyridin-3-yl-phenyl)-4-methyl-7,8-dihydro-6H-quinazolin-5-one oxime, compound 89, (100 mg, 0.275 mmol), 3-dimethyl-aminopropyl chloride hydrochloride (52 mg, 0.330 mmol) and sodium hydride (60% dispersion in oil) (35 mg, 0.881 mmol) following the same procedure used for 2-amino-7-(4-fluoro-biphenyl-2-yl)-4-methyl-7,8-dihydro-6H-quinazolin-5-one O-(3-dimethylamino-propyl)-oxime (compound 88) except after addition of water the solvent was removed under reduced pressure. The crude material was then extracted with ethyl acetate (20 ml), filtered and the resulting organic phase was concentrated under reduced pressure. The resulting material was washed with diethyl ether yielding the title compound.
