4-[(4-Chlorophenyl)methyl]-1(2H)-phthalazinone Use and Manufacturing

Methods of Manufacturing

Intermediate 77 (Stage 2) Isobenzofuran-l(3H)-one (0.50 g, 1.0 eq.) was dissolved in methanol (2.0 mL) and ethyl acetate (10.0 mL) and then 4-chlorobenzaldehyde (0.52 g, 1.0 eq.) was added thereto. NaOH (0.60 g, 4.0 eq.) was dissolved in methanol (8.0 mL) and added to the reaction solution. The mixture was then stirred overnight at 80°C. After confirming the disappearance of the starting material by TLC, the reaction solution was concentrated under reduced pressure. Water and ethyl acetate were added to the obtained residue, and the extracted organic layer was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. Hydrazine hydrate (20.0 mL) was added to the obtained residue, followed by stirring overnight at 80°C. The reaction solution was cooled at room temperature and concentrated under reduced pressure. Ethanol (10.0 mL) was added to the obtained residue and cooled to 0°C using ice. After confirming that a transparent red solid was crystallized, it was filtered to obtain the desired intermediate 4- (4-chlorobenzyl)phthalazin-l(2H)-one (0.25 g, yield 24.8percent).

Uses

Stilbene-related heterocyclic compound with anti-HIV activity. A potent vasorelaxant agent.
