Abstract
The invention comprises compounds of the formulae: <FORM:0856460/IV(b)/1> (wherein R1 is alkyl, alkoxy or halogen, R2 is alkylene, R3 is hydrogen or alkyl and R4 is alkyl, or R3 and R4 may form, together with the nitrogen atom, a saturated heterocyclic ring which may contain another hetero atom), and their preparation by the following methods-(1) reacting the appropriate substituted naphthylamines with haloformic acid-haloalkyl esters X.COO.R2X (X being a halogen atom) and then condensing the N-(substituted-naphthyl)-carbamic acid-haloalkyl esters so formed with amines NHR3R4; or (2) for compounds wherein R3 is alkyl, reacting the appropriate substituted naphthylamines with haloformic acid-aminoalkyl esters X.COO.R2NR3R4 or reacting the appropriate N-(substituted-naphthyl)-carbamic acid halides or substituted-naphthyl isocyanates with amino-alcohols HO.R2.NR3R4, or by re-esterifying the appropriate N-(substituted naphthyl)-carbamic acid alkyl esters with the same amino-alcohols; or (3) for compounds wherein R3 is hydrogen, debenzylating, by catalytic hydrogenation, the corresponding compounds wherein R3 is benzyl. Examples describe the preparation of the 2-(methylamino)-ethyl, 2-(hexamethyleneimino)-ethyl, 2-(diethylamino)-ethyl, 2-(di-n-butylamino) -ethyl, 2-(dimethylamino)-1-methyl-ethyl, 2-(piperidino)-ethyl and 2-(morpholino)-ethyl esters of 2-methyl-naphthyl-1-carbamic acid, the 2-piperidino)-ethyl ester of 2-ethoxy-naphthyl-1-carbamic acid, the 2-(piperidino)-ethyl and 2-(hexamethyleneimino)-ethyl esters of 2-n-butoxy-naphthyl-1-carbamic acid and of 2-chloronaphthyl-1-carbamic acid and the 2-(piperidino)-ethyl ester of 1-methyl-naphthyl-2-carbamic acid. Hydrochlorides of these products are also described. 2-Methyl-naphthyl-1-carbamic acid-b -( (N-methyl-N-benzylamino)-ethyl ester hydrochloride is prepared from 2-methyl-naphthyl-1-isocyanate and N-methyl-N-benzyl-amino-ethanol and then hydrogen chloride. Specifications 717,211, 717,212, 717,213, 717,214 and 734,745 are referred to.
