Reaction Conditions

Reaction Steps

A solution (1 mL) of the compound (560 mg, 2.28 mmol) of Step 1 in N-methyl-2-pyrrolidinone was irradiated with a microwave in a tightly-sealed container, and stirred at 200° C. for 1 hour. To the reaction solution, ethyl acetate and hexane were added. After washing with water and saturated brine, the resultant was dried over anhydrous magnesium sulfate. The solvent was distilled away under reduced pressure. The residue was purified by silica gel chromatography. To the resulting compound (368 mg, 1.50 mmol), formic acid (2 mL) and water (0.2 mL) were added, and stirred at 100° C. overnight. The reaction solution was diluted with ethyl acetate, and after washed with water and saturated brine, the resultant was dried over anhydrous magnesium sulfate. The solvent was distilled away under reduced pressure. The resulting residue was purified by silica gel chromatography (hexane/ethyl acetate) to thus obtain the title compound.
