Reaction Steps

A suspension of 9.00 g of 7-chloro-1,10a-dihydropyrrolo[1,2-b]isoquinoline-3,10[2H,5H]-dione in 95% ethanol (65 ml) was treated with a premixed solution prepared from 10.40 g of sodium acetate trihydrate in water (35 ml) and 5.31 g of hydroxylamine hydrochloride in water (35 ml). The suspension was heated to reflux and after 10 minutes a solution formed. After 1 hour of refluxing, a precipitate began to form and heating was continued for another 1.5 hours, after which time the mixture was allowed to cool to ambient temperature. The precipitate was isolated by vacuum filtration and dried under vacuum at 40° C. The solid was recrystallized form n-propanol (300 ml) to give 6.45 g of crystals, m.p. 249°-252° C.
