A mixture of the 23.6% toluene solution of o-nitrophenyl cyclopropyl ketone obtained in Example 7 (232.3 g, 0.286 mole ketone) and 2.86 g of 5% Pd/C catalyst is placed under H2 at 32-56 psig in a Parr hydrogenator. The hydrogen uptake is monitored and when the reaction is complete, the reaction mixture is filtered and concentrated in vacuo to give the title product, 39.5 g, 86.3% pure by HPLC analysis (73.9% yield).
