Reaction Steps

N-(1-Benzyl-4-methylhexahydro-1H-1,4-diazepin-6-yl)-1H-indazole-3-carboxamide (850 mg) is dissolved in ethanol (40 ml) and hydrogenated over 10% palladium on carbon (100 mg) at about 50° C. After the calculated amount of the hydrogen is absorbed, the catalyst is filtered off. The filtrate is evaporated under reduced pressure to give the title compound as an oil. The free base thus obtained is converted to the oxalate 3/2 hydrate of the title compound in a usual manner, m.p. 163°-166° C. (recrystallzed from ethanol-diethyl ether).
