YieldReaction ConditionsOperation in experiment
39% With hydrazine dihydrochloride; In ethanol; at 20℃;Reflux; Step 2: lH-Pyrazole-3-carboxylic acid ethyl ester[0164] 4-Dimethylamino-2-oxo-but-3-enoic acid ethyl ester (195 g, 1.14 mol) and hydrazine dihydrochloride (119.7 g, 1 eq) were dissolved in EtOH (1 L) and stirred at room temperature overnight. The mixture was then heated to reflux for 2 hours. The reaction mixture was allowed to cool to room temperature and filtered. The solid was washed with water three times and dried. The filtrate was concentrated to a thick oil and added dropwise into a flask with stirred EtOAc (200 mL). The resulting solid was filtered and rinsed with a small amount of EtOAc. The filtered solids were combined to give the product (62 g, 39percent yield). MS (ES) mlz 141.1 (M+ H+).
