Reaktionsschritte

To a 1 liter, four-necked flask equipped with nitrogen inlet, thermometer, and mechanical stirrer was charged 499.74 g (490 ml, 3.84 mol) of ethyl acetoacetate and 12.9 g (0.115 mol) of potassium-t-butoxide. The resulting mixture was stirred while 391 g (4.04 mol) of trifluoroaceto-nitrile was added. The reaction mixture was washed with hexane and the resulting solid was dried in vacuo affording 535 g (62%) of the enamine as a yellow solid; mp 63°-65° C.
