Abstract
Quaternary ammonium compounds are obtained from urea derivatives of the formula RR1NYNHCONH2, in which R and R1 are alkyl groups or RR1N is the residue of a heterocyclic secondary base, and Y is a group -CH2CH2- or an arylene group, by treating the urea derivatives with an ester derived from a mono- or poly-hydric aliphatic or araliphatic alcohol and an inorganic acid or organic sulphonic acid. Examples are given of the preparation of products from (1) 4-dimethylaminophenylurea and dimethyl sulphate; (2) b -dimethylaminoethylurea and methyl iodide; (3) b -piperidylethylurea and dimethyl sulphate, or (example 4) 1 : 4-dibromobutene - 2, or (example 5) ethylene chlorhydrin; (6) b -dibutylaminoethylurea and benzyl chloride, or (example 7) methyl iodide. Other urea derivatives which may be treated are those of the formula above in which RR1N indicates a morpholine or tetrahydroquinoline residue, and other esters which may be used are methyl chloride and ethyl p-toluenesulphonate. Specification 497,042 is referred to.
