Conditions

Temperature: 95 °C

Procedure

Compound 36 (97.1 mg, 0.240 mmol) was dissolved in DMF (2.5 mL), imidazole (49.0 mg, 0.721 mmol) was added thereto, followed by stirring at 95° C. for 2 hours. The reaction mixture was poured into water, followed by extraction with ethyl acetate. The organic layer was washed with a saturated aqueous solution of sodium chloride and dried over anhydrous magnesium sulfate, and then the solvent was distilled away under the reduced pressure. The resulting residue was purified through silica gel column chromatography (chloroform:methanol=17:3) to afford the entitled Compound 37 (58.0 mg, 55%).
