Reaction Steps

To a solution of 0.05 mole of (cis)-4-(7-Methoxy-2,2-dimethyl-2,3-dihydro-benzofuran-4-yl)-4a,5,8,8a-tetrahydro-2H-phthalazin-1-one (starting compound A12) and 0.15 mole of sodium hydride in 100 ml of dimethylformamide is stirred at RT for 30 min, after which 0.05 mole of 4-chloromethylbenzoic acid is added. This mixture is left stirring for 18 h, after which it is poured into water. This solution is acidified with hydrochloric acid and subsequently extracted with dichloromethane. The organic solution is dried over magnesium sulfate and evaporated. The compound is crystallized from diethyl ether.
