Sodium hydride → 2-Amino-7-biphenyl-2-yl-4-methyl-7,8-dihydro-6H-quinazolin-5-one O-[3-(4-methyl-piperazin-1-yl)-propyl]-oxime

Participants

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, (100 mg, 0.290 mmol), 1-(3-chloro-propyl)-4-methyl-piperazine dihydrochloride (87 mg, 0.348 mmol) and sodium hydride (60% dispersion in oil) (52 mg, 1.31 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 ethylacetate (20 ml) and the resulting solution was filtered. The solvent was removed under reduced pressure and the title compound was purified by column chromatography eluting with dichloromethane/methanol (90/10).
