Versuchsvorschrift

Raney nickel (6 g) was slurried in ethanol (100 mL) and a solution of 2-phenylindolizine (48 g, 0.24 mol) in ethanol (1 L) was added. The reaction mixture was stirred under hydrogen at room temperature and 50-60 psi overnight. The mixture was filtered through Celite then the solvent was evaporated under vacuum to yield 2-phenyl-5,6,7,8-tetrahydro-indolizine (32 g, 65%) as a white solid.
