Reaction Steps

The title compound was prepared from 2-amino-7-biphenyl-2-yl-4-methyl-7,8-dihydro-6H-quinazolin-5-one oxime, compound 66, (50 mg, 0.145 mmol), 6-chloro-1-hexyne (21 μl, 0.174 mmol) and sodium hydride (60% dispersion in oil) (11 mg, 0.465 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 taken up in methanol (20 ml) and the resulting solution was filtered. The solvent was removed under reduced pressure. The title compound was purified by preparative HPLC (mass directed fraction collection).
