Versuchsvorschrift
Compound 1 (1.00 g, 2.42 mmol) obtained in Reference Example 1 was dissolved in 1.6 L of methanol, and the solution was irradiated with sunlight for 5 hours. After evaporation under reduced pressure, the residue was purified by high performance liquid chromatography (column: YMC Pack ODS-A, SH-365-10, S-10; 30 mm.O slashed.×500 mm, flow rate: 90 ml/min, detection: UV 246 nm) to give 565 mg (yield 57%) of Compound 186 as white needles.
