Reaction Steps

A mixture of 1-(3-Chloro-6-pyridazinyl)-homopiperazine (5.56 g, 26.1 mmol), palladium on carbon (2.1 g, 10%) and ethanol (150 ml) was stirred under hydrogen overnight. The crude product was filtered through celite and evaporated. Chromatography on silica gel with dichloromethane, methanol and conc. ammonia (89:10:1) gave the title compound as free base. Yield 2.78 g, 60%, 185.0-186.9° C.
