To methanol (300 mL) solution of the compound obtained in Example 125 (3.6 g) was added 5% palladium/carbon (0.36 g) in an argon atmosphere, and the mixture was stirred for 16 hours at room temperature in a hydrogen atmosphere. The catalyst was filtered off, and the solvent was distilled off under a reduced pressure, to give the captioned compound (2.1 g, 95%) as an oily product.
