Versuchsvorschrift

In 7 ml of tetrahydrofuran, 703 mg of Compound 5-1 obtained in Production Example 9 of Example 1 was dissolved. To the solution thus obtained, 7 ml of methanol and 5 ml of 25% aqueous solution of sodium hydride were added, and the resulting mixture was refluxed in hot water bath of 80° C. for 5 hours. After the reaction, the solvent was distilled away, and the residue was then mixed with water.
