In 100 ml of toluene, 2 g of the starting ketone, 2.12 g of pyrrolidine and 0.14 g of boron trifluoride etherate were dissolved. The mixture was refluxed for 47 hours under argon atmosphere using a Cope water separator and molecular sieve 4A as the dehydrating agent. After having distilled out the solvent, the residue was subjected to a distillation under a reduced pressure to obtain 0.95 g of the desired enamine (yield: 34%).
