Versuchsvorschrift

2-(4-Methyl-2H-phthalazin-1-on-2-yl)ethyl bromide (6.1 g) and methylamine (20 ml of 30% ethanolic methylamine) in ethanol (150 ml) were heated in a bomb at 100° for 2 hours. The solvent was removed and the residue triturated with ethyl acetate to give a yellow solid, which was recrystallised from ethanol to afford the title compound, yield 5.03 g, m.p. 219°-221°.
