Procedure

The compound obtained in Example 6 was dissolved in water and methanol, to which a catalyst amount of Pd/C was added, and the resultant was stirred for three days in a hydrogen atmosphere. After filtrating the catalyst, the solvent was distilled away, and the resultant was purified using purification step A to obtain the title compound.
