Abstract

283,822. Stephens, A. J., (Wulfing, R. von). Sept. 23, 1927. 2-Phenylquinoline-4-carboxylic acid is prepared by heating isatine-bisulphite of sodium or potassium and acetophenone in the presence of excess of caustic soda or potash solution. In an example, isatine-bisulphite of sodium or isatine and sodium bisulphite are dissolved in hot water and caustic soda and acetophenone are added. Specification 17725/14 is referred to.
