7-OXO-7H-dibenzo-[d e,h]-quinolin-2-ol which is useful as an intermediate in the preparation of dyestuffs is prepared by cycloisomerizing the novel compound, N-phenylacetyl phthalimide in an inert solvent and in the presence of a Friedel-Crafts catalyst to form the novel compound O-(3-hydroxy-1-isoquinolinyl)-benzoic acid which is then cyclized by dehydrating condensation to form the 7-oxo-7H-dibenzo-[d e,h]-quinolin-2-ol.
