Participants

Reaction Steps

Acetoacetic cyclopentylamide (169.1 g, 1.00 mole) is dissolved in ethanol (100 ml) and thereto is passed ammonia gas, while the temperature is controlled below 30° C. by cooling with a water bath. After passing ammonia gas for about 3 hours, colorless crystals precipitate. The reaction mixture is allowed to stand at 0° C. overnight. The precipitates are separated by filtration and washed with diethyl ether to give the title compound (140.4 g, yield 85.6%) as colorless needles, m.p. 138°-139° C.
