Benzyl Alcohol → HCID 18770464, compound

Participants

Reaction Steps

Triethylamine (0.39 ml; 2.8 mmol), diphenylphosphoryl azide (0.61 ml; 2.8 mmol) and benzyl alcohol (0.39 ml; 3.8 mmol) were added to a solution in toluene (10 ml) of 2,2-bis[(1-tert-butoxycarbonyl-4-piperidinyl)methyl]acetic acid (850 mg; 1.9 mmol) synthesized by the above process, and the mixture was stirred for 12 hours in a bath controlled at 100° C. The reaction mixture was concentrated under reduced pressure, and the resultant concentrated residue was dissolved in ethyl acetate. This solution was washed successively with a saturated aqueous solution of sodium hydrogencarbonate and 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 639 mg (yield: 61%) of 2-benzyloxycarbonylamino-1,3-bis(1-tert-butoxycarbonyl-4-piperidinyl)propane as a colorless oil.
