Versuchsvorschrift
Compound (29) 609 mg was dissolved in tetrahydrofuran 20 ml. 20% Palladium(II)hydroxide 200 mg was added. A mixture was stirred in a hydrogen atomosphere for 22 h. The catalyst was filtered off and the filtrate was concentrated under reduced pressure. The residue obtained was chromatographed on aluminum oxide in chloroform to give the titled compound (31) as pale brown crystals, 337 mg. Yield 86%. Furthermore, this was recrystallized from methanol-isopropanol to give the titled compound (31) as pale brown crystals, m.p. 202-203° C.
