PROCEDURE

实验过程

2-(4-Methyl-2H-phthalazin-1-on-2-yl)-N-methylethylamine hydrobromide (2 g), 4-methanesulphonamidophenacyl bromide (1.8 g) and triethylamine (1.5 g) in ethanol (50 ml) were stirred at room temperature for 2 hours. The solvent was removed, the residue taken up in methylene chloride (100 ml), washed (aqueous sodium bicarbonate), dried (MgSO4) and evaporated. Chromatography on silica [Merck `Kieselgel 60` (Trade Mark)] eluting with methylene chloride containing methanol (0% up to 5%) gave, after collection and evaporation of appropriate fractions, an oil which was triturated with ethanol to give the title compound, yield 1.63 g, m.p. 176°-179°.
