실험 절차

Diisopropyl azodicarboxylate (63 mg) was added to a solution of the compound obtained from Example 1A above (100 mg), tri-n-butylphosphine (93 mg), and acetic acid (1 mL) in dry tetrahydrofuran (3 mL) at 0° C. The reaction mixture was stirred for 1 hour and concentrated. The residue was taken in ethyl acetate, and washed with water and brine. The organic layer was concentrated to get an oily residue which was purified on preparative thin layer chromatography (2 mm thickness) using 10% methanol in dichloromethane to get the title compound (80 mg).
