To a solution of [1-((E)-3-Dimethylamino-acryloyl)-cyclopropyl]-carbamic acid tert-butyl ester (600 mg, 2.4 mmol) was added triethylamine (1.3 mL, 9.4 mmol) and formamidine hydrochloride (570 mg, 7.1 mmol) at room temperature. The reaction was stirred at 75-80° C. for 14 h. The volatiles were removed in vacuo to give a crude solid mass that was purified by preparative reversed phase HPLC to give 115 mg of the title compound as a light yellow solid, m/z 236.36 [M+1]+.
