Dichloroacetyl chloride → HCID 19826626, compound

Participants

Reaction Steps

A solution of 14.7 g of dichloroacetylchloride in 10 ml of toluene are added dropwise, while stirring at a temperature of -10° to 15° C. to another solution of 20.6 g of N-(3,4-dimethoxy-α-cyanobenzyl-N-methylamine (prepared according to J. Prakt. Chem. 285 (1961) p. 258) in 80 ml of toluene and 20 ml of water, in which was dissolved 4 g of solid NaOH. A solid reaction product precipitates, which is filtered and washed with water until the aqueous filtrate is neutral. The solid acid amide is dried under vacuum to yield 27.7 g of raw product melting at 102°. After treating it with charcoal and recrystallisation from ethanol one obtains 125 g of crystalline title product, melting at 111°-112°.
