Reaction Steps

The compound obtained in Example 157 (0.85 g, 2.88 mmol) dissolved in dioxane (50 ml) was combined with 10% palladium-carbon (1.55 g), then stirred in the stream of hydrogen at 60° for 16 hours. From the reaction mixture, palladium-carbon was filtered off. The filtrate was condensed under reduced pressure, and the reside was washed with ether. 0.726 g of the tile compound was obtained as pale brown crystals (84.8%). They were recrystallized from a solvent mixture of chloroform--methanol--ether to obtain colorless prisms of the title compound (mp.: 209°-210° C. (dec.)).
