実験手順

A mixture of 3.0 g (23.8 mmol) of cyclohexyl methyl ketone and 4.56 g (26.2 mmol) of t-butoxybis(dimethylamino)methane (Bredereck's reagent) was stirred at 60□C overnight. The reaction mixture was then concentrated to give 4.0 g (93% yield) of 1-cyclohexyl-3-dimethylamino-propenone as an orange oil as indicated by 1H NMR. This product was used in the next reaction without any further purification.
