Reaction Steps
Under an argon atmosphere, the compound prepared in Example 18 (79 g) was dissolved in 1,2-dimethoxyethane (500 mL). The reaction mixture was added with anhydrous N,N-dimethylformamide (3 drops) and oxalyl chloride (24 mL), and stirred at 40° C. for an hour. The reaction mixture was concentrated to obtain the title compound.
