Procedure

An autoclave was charged with 112 mg of 1-(1-t-butoxycarbonylamino-1-cyanomethyl)-1-ethoxycarbonylcyclopropane, 0.5 ml of Raney nickel and 3.0 ml of ammonia-saturated ethanol, and the contents were stirred at 80° C. for 2 hours in an atmosphere of hydrogen under a pressure of 65 kg/cm2. After completion of the reaction, the catalyst was removed by filtration and the resulting filtrate was concentrated under a reduced pressure to obtain 86 mg (91%) of the title compound in the form of colorless crystals. The thus obtained compound was recrystallized from ethyl acetate and diethyl ether, and used as a sample for analyses.
