Reaction Steps

A solution of ethyl(E)-3-(dimethylamino)-2-methylprop-2-enoate (668 mg, 4.25 mmol) and 2-hydrazinylpyridine-4-carbonitrile (570 mg, 4.25 mmol, PREPARATION 2) in 2 mL HOAc and 10 mL EtOH was charged to a flask and the mixture was heated to 90° C. for 30 min. Cooled to room temperature and removed the solvent. The residue was dissolved in ethylacetate and water, aqueous basified with NaHCO3 sat (pH=8), extracted with ethylacetate. The organic phase was washed with brine and dried with anhydrous sodium sulfate and then purified by silica gel chromatograph to give 0.65 g of the title compound (62%). [M+H] Calc'd for C12H14N4O2, 247; Found, 247.
