Reaction Steps

(2Z)-3-amino-2-butenenitrile (903 mg, 11.00 mmol), cyclopropylhydrazine (1194 mg, 11 mmol) and triethylamine (3.07 mL, 22.00 mmol) were suspended in ethanol (100 mL) and heated to 70° C. for 16 hours. The solvent was removed in vacuo. The residue was suspended in 50 mL of saturated NaHCO3 and stirred for 10 minutes. The contents were extracted with DCM, dried over MgSO4, filtered, and concentrated in vacuo. The residue was purified by silica gel chromatography (eluent: 0% to 100% gradient EtOAc:Hex). The product was collected as 310 mg. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 0.95-1.13 (m, 4 H), 2.13 (s, 3 H), 3.06 (m, J=6.95, 6.95, 3.79, 3.54 Hz, 1 H), 3.76-3.88 (m, 2 H), 5.24 (s, 1 H).
