| abstract | 1353964 Preparation of substituted α-naphthoxyacetamides STAUFFER CHEMICAL CO 1 Nov 1971 [2 Nov 1970] 50685/71 Heading C2C α-Naphthoxy acetamides of formula (wherein R 1 is hydrogen or (C 1-6 ) alkyl, R 2 is hydrogen, (C 1-6 ) alkyl or (C 2-6 ) alkenyl, and R 3 is (C 1-6 ) alkyl or (C 2-6 ) alkenyl; provided that when R 1 and R 2 are both hydrogen, R 3 is alkyl having 1 or 2 carbon atoms or (C 2-6 ) alkenyl, comprising: (a) treating an acid of formula wherein R 1 is as defined above, with phosgene or thionyl chloride or mixtures thereof, to form the acid chloride of α-naphthoxy propionic acid; the phosgene or thionyl chloride being used in a stoichiometric excess and the reaction being carried out in the presence of dimethyl formamide or triethylamine hydrochloride catalyst; (b) treating the acid chloride with N,N-dialkylamine in stoichiometric excess to form the endproduct, said alkyl group having 1 to 5 carbon atoms. N,N-Diethyl-2-(α-naphthoxy)-propionamide is prepared in the Examples. The intermediate α-Naphthoxypropionic acid is prepared by reacting α-naphthol with α-chloropropionic acid. |
