Reaction Conditions

Reaction Steps

1.8 ml (15.0 mmol) of benzoyl chloride was added to 15 ml of pyridine solution containing 278 mg (1.0 mmol) of the compound of Example 43, and the mixture was stirred at 80° C. for 10 days. The reaction solution was concentrated under a reduced pressure, chloroform was added to the resulting residue, followed by washing with water and drying over anhydrous magnesium sulfate. The solvent was evaporated, the resulting residue was purified by a silica gel column chromatography. Then, the resulting crude crystals were recrystallized from ethanol-diisopropyl ether to give 241 mg of the title compound.
