Procedure

13.5 g (292 mol) of methylhydrazine were added slowly to 80.4 g (292 mmol) of ethyl 2,4-dichloro-5-methylbenzoylacetate in 300 m of diethylene glycoldimethyl ether. The reaction solution was heated at 100° C. for 4 hours and then stirred into 11 of ice-water. The precipitate formed was filtered off, washed with a little-methylene chloride and dried. Yield: 38.8 g; m.p. 196°-198° C.;
