6-[2-(4-methoxyphenyl)ethenyl]-2-[3-(dimethylamino)propyl]phthalazin-1(2H)-one (9 gm) was dissolved in 200 ml methoxyethanol and reduced on a Parr hydrogenator using 1 gm of 10% palladium on carbon as catalyst. Reduction was complete within 2 hours. The catalyst was filtered off, the solvent removed on a rotary evaporator and the residue recrystallized from 500 ml of isoproanol. The product weighed 8.3 gm and melted at 201°-203° C.
