The hydrohalide of an amide or ketone having the general formula: <FORM:0765544/IV(b)/1> wherein R is a hydrogen atom or an alkyl, aryl or aralkyl group, R1 is an aryl group or an aryl-amino group which may contain alkyl groups or halogen atoms as nuclear substituents and/or an alkyl substituent on the nitrogen atom of the amino group, R2 and R3 are both alkyl or cycloalkyl groups or together represent a polymethylene or alkyl-substituted polymethylene group, and Hal is a halogen atom, is prepared by treating an amide or ketone R.CH2.COR1 with an N-halogeno secondary amine R2.N(Hal).R3 in an inert solvent. Suitable solvents are dialkyl ethers, cyclic ethers or carbon tetrahalides. If an acid acceptor is present in the reaction the product is a free base. Acid acceptors referred to are an excess of the secondary amine, a tertiary amine and an alkali metal salt of a weak acid. Amine starting materials referred to are N-chlordimethylamine, N - chlormethylethylamine, N - chlordiethylamine, N - chlordi - n - propylamine, N - chlordi - p - butylamine, N - chloropiperidine and N-chlorodicyclohexylamine. Ketone starting materials include acetophenone, propiophenone, methyl tolyl ketone, ethyl tolyl ketone and methyl xylyl ketone, and amide starting materials include acetanilide, aceto-ortho-toluidine, acet - para - toluidide, acet - 2.4 - xylidide, acet-2,6 - xylidide, propionanilide propion - 2.4-xylidide, propion - 2.6 - xylidide, orthochloroacetanilide, para - chloroacetanilide, 2.4-, 2.5 - dichloroacetanilide and 2.4, 6 - trichloroacetanilides, para - chloropropionanilide, N - methylacetanilide and N - ethylacetanilide. Examples describe the preparation of 2.6-dimethyl - N.N. - diethyl glycylanilide, 2.5 - di - chloro - N.N. - di - n - propyl alanylanilide, a -piperidinopropiophenone hydrochloride and a -dimethylaminodesoxybenzoin. Starting materials. N-Halogeno secondary amines are prepared from the appropriate secondary amine and a cold aqueous solution of an alkali metal hypohalite, preferably in the presence of a solvent for the amine.
