Reaction Steps

To a mixture of ethyl 3-(4-chlorophenyl)-3-oxopropanoate (500 mg, 2.2 mmol) and 2-hydrazinylpyridine-4-carbonitrile (PREPARATION 2, 296 mg, 2.2 mmol) in EtOH (15 mL) was added AcOH (2 mL) at r.t. The reaction mixture was stirred at 90° C. overnight. After the reaction was completed, the mixture was concentrated, washed with PE/EA (10 mL, V/V=1/1) to give the title compound (500 mg, 76%) as a brown solid and used as crude for next step.
