Reaction Steps
To a solution of the compound obtained in Example 588 (0.050 mg) in DMF (1 mL) were added potassium carbonate (0.0166 mg) and 2-pyrrolidinone (0.0093 mL), and the mixture was stirred at 110° C. for 1 hr. To the reaction mixture was added water, and the resultant product was extracted with ethyl acetate. The organic layer was washed with brine and dried, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (NH Chromatorex) (solvent gradient; 30→100% ethyl acetate/hexane) to give the title compound (37 mg, 63%) as a white powder.
