Conditions

Temperature
160 °C

Procedure

300 mg of the compound (197) obtained in Example 68 was dissolved in 6 ml of N-methylpyrrolidone, and the solution was heated at 160° C. for 3 hours. After air-cooling, the water was added to the reaction solution, and the solution was extracted with chloroform three times. After drying over magnesium sulfate, the solvent was removed by distillation. The residue was separated by column chromatography (silica gel, eluent solvent; chloroform) to obtain 128 mg of the subject compound (198) in a 49% yield.
