Participants

Reaction Steps

5-Hydrazino-1,3-dihydropyrrolo[4,3,2-de]isoquinoline (4.5 g), described in Example 8, is boiled in acetone (ca. 50 ml) for 10 minutes. The reaction mixture is treated with charcoal, filtered and concentrated. Addition of ether-hexane gives a precipitate. The precipitate is recrystallized from benzenemethanol-ether to give the title compound, mp 200° - 201°C, νmaxnujol 3450, 3100, 1625, 1565, 1540 and 1510 cm-1.
