実験手順

To a solution of 5-[(4-cyclohexyl-phenylamino)-methyl]-4,5-dihydro-oxazol-2-ylamine (1.13 g, 4.14 mmol) in 50 ml of ethanol was added 0.42 ml (0.415 mmol) of ethyl propiolate. The mixture was stirred at reflux for 6 h under nitrogen after which it was allowed to cool to room temperature. The resulting white crystals were isolated by filtration, washed with ethanol, and dried at room temperature under high vacuum to provide 0.294 g of the title compound. The filtrate from the filtration was concentrated to 10 ml and allowed to stand for 6 h. The resulting white crystals were isolated by filtration and dried under high vacuum to provide an additional 0.059 g of the title compound.
