| abstract | The invention comprises anaethestics of the formula <FORM:0717214/IV (b)/1> where R1 and R3 are alkyl or alkoxy groups, R2 is hydrogen or an alkyl or alkoxy group, R4 is a hydrocarbon chain of up to 6 carbon atoms, and R5 and R6 are hydrogen or alkyl groups which, with the nitrogen, may form a heterocyclic ring. They may be prepared by reacting an isocyanate of the formula <FORM:0717214/IV (b)/2> with an amino alcohol of the formula <FORM:0717214/IV (b)/3> with or without an inert solvent, e.g. benzene or toluene, first with cooling and then by boiling for one or two hours. The amino alcohol may be used in the form of its salt. In the examples: (1) 2,6-dimethyl-4-tert.-butyl carbanilic acid-b -piperidino-ethyl ester is prepared from 2,6-dimethyl-4-tert.-butyl phenyl isocyanate and b -piperidino-ethyl alcohol; (2) 2,6-dimethyl-4-n-butoxy carbanilic acid-g -diethylamino-propanol ester from 2,6 - dimethyl - 4 - n - butoxy phenyl isocyanate and 3-diethylaminopropanol-1; (3) 2,4,6-trimethyl-carbanilic acid-b -diethylamino ethyl ester hydrochloride is prepared from 2,4,6-trimethyl phenyl isocyanate and diethylaminoethyl alcohol. U.S.A. Specification 2,109,492 is referred to. |
