Reaction Steps

IV (1.74 g, 0.0048 mole), ethanol (25 ml), and Raney copper (Ponomarev et al., J.Gen.Chem. USSR 30 (1960) 584) (0.75 g) were shaken under 80 atmospheres of hydrogen for 6 hours at 30°C. After filtration, the ethanol was distilled under reduced pressure from a water bath (60°C). Ether (30 ml) was added to the residue, and the turbid solution was filtered (G4, Celite). The ethereal solution was evaporated to dryness from a water bath (50°C) under reduced pressure, at last under 15 mm Hg. The residual oil was purified by distillation under nitrogen. 1.51 g (86%) of V was hereby obtained as an almost colorless oil, b0.2 178°-181°C, nD25 1.4700.
