실험 절차

A mixture of 0.432 g (0.95 mmol) of the product of Step B, 250 A (1.67 mmol) of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) in 2 mL DMF was placed in a 10 mL reaction tube of a CEM Corporation Discover 300 Watt microwave reactor. The reaction vessel was sealed, placed in the microwave reactor and heated at 150° C. for 10 min. After the reaction mixture had cooled to room temperature, it was partitioned between EtOAc and 10% aq. NaHSO4 and extracted. The organic layer was washed with 10% aq. NaHSO4, water, brine, dried (MgSO4), filtered and evaporated. The residue was purified on a silica gel flash chromatography column eluted with 0–10% EtOAc-hexane. Evaporation of the purified fractions and drying in vacuo afforded the title compound. HPLC/MS: 438.1 (M+1), 440.1 (M+3); Rt=4.72 min.
