Procedure

To a DMF (1.0 mL) solution of the compound (30 mg) obtained in Example 3-(5) and pyridin-2-ol (12 mg), K2CO3 (35 mg) was added and the mixture was stirred at 50° C. for an hour. To the reaction mixture, DMSO (1.0 ml) was added and after filtering off the insoluble matter, the filtrate was purified by reverse-phase preparative HPLC to give Compound 54 (2.0 mg, colorless oil) and Compound 60 (16.0 mg, colorless oil.)
