Reaction Steps
After a 4N hydrogen chloride in ethyl acetate (5 ml; 20 mmol) was added to a solution in methylene chloride (3 ml) of N,N-bis[(1-tert-butoxycarbonyl-4-piperidinyl)-methyl]methylamine (640 mg; 1.5 mmol) synthesized by the above process under ice cooling. The ice bath was removed, and the mixture was stirred at room temperature for 1 hour. The reaction mixture was concentrated under reduced pressure, and the resultant crude crystals were recrystallized from methanol-diethyl ether, thereby obtaining 412 mg (yield: 82%) of the title compound as colorless needles (melting point: 280° C. or higher).
