Under hydrogen atmosphere, a suspension of 1.80 g of the compound obtained in Step 11-3 and 360 mg of 10% palladium-carbon in MeOH (36 ml) was stirred at room temperature for 3 hours. From the stirred solution, insoluble matter was separated by filtration, the solution was concentrated under reduced pressure to obtain 1.07 g of the title compound. The present compound was used in the next reaction without purification.
