Reaction Steps

In 50 ml of benzene, 9.38 g of propiophenone, 14.93 g of pyrrolidine and 0.99 g of boron trifluoride etherate were dissolved. The mixture was refluxed for 67 hours using a Cope water separator and molecular sieve 4A as the dehydrating agent. After having distilled out the solvent under a reduced pressure, the residue was subjected to a distillation under a reduced pressure to obtain 10.33 g of the desired enamine (yield: 79%).
