Procedure

Under argon atmosphere, the compound (400 mg) prepared in Example 9 was dissolved to 1,2-dimethoxyethane (6.0 mL). Anhydrous N,N-dimethylformamide (one drop) and oxalyl chloride (0.22 mL) were added to the reaction mixture, which was stirred for 30 minutes at 40° C. The title compound was obtained by concentrating the reaction mixture.
