Procedure

A solution of 2.2 g. of 1-allyl-4-hydroxy-naphthpyridine-2(1H)-one-3-carboxylic acid t-butyl ester in 25 ml. of acetonitrile is treated with 0.75 ml. of 60% aqueous perchloric acid at 0° C. The resulting precipitate is filtered off and cooled with ester to obtain 1-allyl-4-hydroxy-naphthpyridine-2(1H)-one-3-carboxylic acid.
