Procedure

13.5 g (292 mmol) of methylhydrazine were slowly added to 80.4 g (292 mmol) of ethyl 2,4-dichloro-5-methylbenzoylacetate in 300 ml of diethylene glycol dimethyl ether. After 4 hours at 100° C., the solution was stirred into 1 l of ice-water. The precipitate formed was filtered off, washed with a small amount of methylene chloride and dried. Yield: 38.8 g.
