Pd—C (371 mg) was added to a solution of Compound 30 (3.7 g) in methanol (111 mL) and then, hydrogenation was carried out by stirring the mixture at atmospheric pressure and room temperature overnight. Subsequently, the catalyst was removed by filtration and the filtrate was concentrated under reduced pressure to give 2.9 g (96% yield) of the title compound.
