Procedure

In a manner similar to Example 4, Step (c), (4′-methoxy-biphenyl-4-yl)-4-oxo-butyric acid (1.08 g, 0.00380 mol) was allowed to react with hydroxylamine hydrochloride (0.316 g, 0.00455 mol) in the presence of sodium carbonate (0.485 g, 0.00458 mol) in absolute ethanol (20 mL) to give 0.983 g of 4-hydroxyimino-4-(4′-methoxy-biphenyl-4-yl)-butyric acid as a pale yellow solid; mp 157-160° C.
