실험 절차

A solution of 1.0 g of 6-tert-butoxycarbonylamino-1-hexanol in 20 mL of methylene chloride was combined with 3 g of a 4 angstrom molecular sieve, 808 mg of N-methylmorpholine-N-oxide and a catalytic amount of tetrapropylammonium perruthenate, and stirred for 24 hours. The reaction solution was filtered through Celite, and concentrated. The residue was purified by column chromatography on silica gel (n-hexane:ethyl acetate=2:1) to obtain 660 mg of the desirable compound.
