To a solution of 14 g. (44.7 mmoles) of ethyl 2-nitro-4-benzoylphenylacetate in 225 ml. of ethanol was added 15 g. of wet Raney nickel and the mixture heated to reflux for 1.5 hours. The mixture was filtered and the filtrate concentrated to give a residual oil which was induced to crystallize by trituration with diethyl ether, 7.9 g., m.p. 150°-152° C.
