Procedure

To a solution of 2-hydrazinylisonicotinonitrile (100 mg, 0.75 mmol, 1.0 eq., PREPARATION 2) and (E)-3-(dimethylamino)-1-phenylprop-2-en-1-one (132 mg, 0.75 mmol, 1.0 eq.) in ethanol (10 mL) was added 2-5 drops of AcOH. The reaction mixture was under reflux conditions for 12 h. After reaction completion, volatiles were removed under reduced pressure, and the resultant crude material was purified by flash column chromatography (20% EtOAc/hexane) to obtain the title compound as a yellow oil (150 mg, 81% yield). [M+H] Calc'd for C15H10N4, 247.09. Found 247.
