Procedure

55% Sodium hydride (19 mg) and methyl iodide (0.027 ml) were added to a solution of the compound obtained in Step 2 of Example 130 (64 mg) in N,N-dimethylformamide (3.6 ml) in an ice bath, and the mixture was stirred in an ice bath for 2 hours. The reaction solution was separated by adding an aqueous ammonium chloride solution and ethyl acetate. The resulting organic layer was washed with brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The resulting residue was purified by silica gel column chromatography (developed with ethyl acetate-hexane) to give the title compound (73 mg).
