Reaction Steps

To a solution of ethyl (2E)-(1-isopropenyl-6,7-dihydro-8H-pyrido[3,4-b]-pyrrolizin-8-ylidene)ethanoate (0.40 g, 1.4 mmol) in MeOH (20 mL) was added Pd(OH)2 (0.20 g). The mixture was stirred under 1 atm of H2 for 3 h. The mixture was filtered over celite and evaporated to provide the title compound.
