Brain, E. G. published the artcileDerivatives of 6-aminopenicillanic acid. IV. Analogs of 2,6-dimethoxyphenylpenicillin in the naphthalene and quinoline series, Recommanded Product: 3-Chloro-2,6-dimethoxybenzoic acid, the publication is Journal of the Chemical Society (1963), 491-7, database is CAplus.
cf. CA 57, 12458c. A number of sterically hindered alkoxynaphthoic and -quinolinecaxboxylic acids have been synthesized. Reaction of the acid chlorides with 6-aminopenicillanic acid gave substituted naphthyl- and quinolylpenicillins which resisted inactivation by penicillinase.
