| abstract | Diethylcarbamates of resorcinol-monoalkylethers and homologues thereof are prepared by (1) reacting a resorcinol-monoalkylether first with phosgene and then with diethylamine; (2) treating a resorcinol-monoalkylether with diethylcarbamic acid chloride; or (3) alkylating a resorcinol-monocarbamic acid ester which is diethylated at the nitrogen. The products possess vermicidal properties. According to the examples: (1) resorcinol-monomethylether-diethylcarbamate is prepared by treating resorcinol-monomethylether in toluene solution with phosgene in the presence of pyridine and reacting the resulting chlorocarbonic ester with diethylamine in ether solution, or by heating resorcinol with diethylcarbamic acid chloride in presence of pyridine and treating a methanol solution of the monodiethylcarbamate so formed with dimethylsulphate and caustic potash; (2) resorcinol-monoethylether-diethylcarbamate is obtained by heating resorcinol-monoethylether with diethylcarbamic acid chloride; (3) 2 - ethoxy - 4 - hydroxytoluene-diethylcarbamate is formed by first reacting 4-amino-2-cresol-ethyl ether with nitrous acid and the resulting 2-ethoxy-4-hydroxytoluene heated with diethylcarbamic acid chloride; (4) resorcinol - mono - n - butylether - diethylcarbamate results when resorcinol-mono-n-butyl-ether is heated with diethylcarbamic acid chloride. |
