Procedure

A solution of 37 g. of the 3-(p-chlorobenzoyl)-2-naphthol of Step 2, above, in a mixture of 300 ml. of diethylene glycol and 75 ml. of hydrazine hydrate is refluxed for 4 hours. It is then cooled and poured on ice-water to yield a precipitate which is collected by filtration. This solid is crystallized from a mixture of methylene chloride (dichloromethane) and ether (1:3) to yield the title product, m.p. 192°.
