To a solution of 3-(1-methyl-cyclopropyl)-3-oxo-propionitrile (1.0 g, 8.1 mmol) in EtOH (10 mL) is added 4N HCl in Dioxane (10 mL). The mixture is stirred at room temperature for 16 hour. Concentrated under reduced pressure, the residue is dissolved in MeOH (40 mL) and treated with methylhydrazine (0.56 g, 12.2 mmol). The mixture is heated at 80° C. for 16 h. The solution is then concentrated in vacuo and the residue is purified by HPLC give product. MS (ESI) m/z 152.3 (M+1).
