Reaction Steps

Dimethylamine hydrochloride (638 mg; 7.8 mmol), potassium carbonate (1.2 g; 8.7 mmol) and potassium iodide (144 mg; 0.87 mmol) were added to a solution in dimethylformamide (10 ml) of 1,3-bis(1-tert-butoxycarbonyl-4-piperidinyl)-2-(bromomethyl)propane (437 mg; 0.87 mmol) synthesized by the above process, and the mixture was stirred for 4 hours in a bath controlled at 60° C. A 0.1N aqueous solution of sodium hydroxide was added to the reaction mixture to conduct extraction with diethyl ether. The organic layer was washed with saturated brine, dried over anhydrous sodium sulfate and then concentrated under reduced pressure. The resultant crude oil was purified by column chromatography on silica gel, thereby obtaining 243 mg (yield: 60%) of the title compound as a colorless oil.
