Procedure

In a manner similar to Example 4, Step (c), 4-(4′-methyl-biphenyl-4-yl)-4-oxo-butyric acid (1.052 g, 0.003922 mol) was allowed to react with hydroxylamine hydrochloride (0.3245 g, 0.00467 mol) in the presence of sodium carbonate (0.498 g, 0.00470 mol) in absolute ethanol to give 1.006 g of 4-hydroxyimino-4-(4′-methyl-biphenyl-4-yl)-butyric acid as a white solid; mp 176.5-177.5° C.
