Reaction Steps

After pyridine (0.090 ml; 1.1 mmol), carbon tetrabromide (716 mg; 2.2 mmol) and triphenylphosphine (567 mg; 2.2 mmol) were added to a solution in diethyl ether (5 ml) of 2,2-bis[(1-tert-butoxycarbonyl-4-piperidinyl)methyl]ethyl alcohol (476 mg; 1.1 mmol) synthesized by the above process under ice cooling, the ice bath was removed, and the mixture was stirred at room temperature for 12 hours. The reaction mixture was filtered, and the filtrate was concentrated under reduced pressure. The resultant crude oil was purified by column chromatography on silica gel, thereby obtaining 465 mg (yield: 86%) of 1,3-bis(1-tert-butoxycarbonyl-4-piperidinyl)-2-(bromomethyl)propane as a colorless oil.
