Procedure
A mixture of Compound 1 (1.69 g) obtained in Example 1, ethoxycarbonyl chloride (2.5 ml) and pyridine (5 ml) was stirred at room temperature for 16 hours. The reaction solution was subjected to partitioning between chloroform and a 10% aqueous solution of citric acid. The organic layer was concentrated under reduced pressure, and the residue was recrystallized from 2-propanol to give Compound 7 (1.83 g).
