実験手順
4-Amino-7-chloro-2,10-dihydro-2-methylpyrazolo[3,4-b][1,5]benzodiazepine hydrochloride (11.3 g) and potassium carbonate (16.8 g) were heated under reflux in a mixture of ethanol (200 ml) and water (20 ml) for 48 hours. Water (300 ml) was added and the solution cooled. The precipitate was crystallised from acetic acid to give the title compound m.p.>260° C.
