1-naphthylamine with diethyl malonate under reflux. These two compounds were then separately cyclised to 4-hydroxybenzo[h]quinolin-2-(1H)-one in two different reactions in polyphosphoric acid. A series of esters and ethers of the 4-hydroxy group and some 3-substituted derivatives were prepared. The structures of the compounds were confirmed by infra-red NMR spectroscopy and elemental analysis.
