Hydrochloric Acid → HCID 18770418, compound

Participants

Reaction Steps

10% Palladium on carbon (125 mg) and concentrated hydrochloric acid (1.2 ml; 14 mmol) were added to a solution in water-methanol (4 ml-8 ml) of N,N′-bis(1-benzyl-4-piperidinyl)-N,N′-dimethylethylenediamine (757 mg; 1.7 mmol) synthesized by the above process, and the mixture was stirred for 6 hours in a bath controlled at 55° C. under hydrogen. The catalyst was removed from the reaction mixture by filtration, and the filtrate was concentrated under reduced pressure. The resultant crude crystals were washed with ethanol, thereby obtaining 497 mg (yield: 71%) of the title compound as a colorless crystalline powder [melting point: 275° C. (decomposition)].
