실험 절차
In a manner similar to Example 4, Step (c), 4-(2′-fluoro-biphenyl-4-yl)-4-oxo-butyric acid (1.634 g, 0.006001 mol) was allowed to react with hydroxylamine hydrochloride (0.500 g, 0.00720 mol) in the presence of sodium carbonate (0.763 g, 0.00720 mol) in absolute ethanol to give 1.434 g of 4-(2′-fluoro-biphenyl-4-yl)-4-hydroxyimino-butyric acid as a pale yellow solid; mp 150.0-151.5° C.
