実験手順
Potassium carbonate (0.21 g), benzyl chloride (0.15 g) and DMF (2 ml) were added to 2-(4-chlorobenzyloxy)-α-(1-imidazolyl)benzaldehyde oxime (0.33 g), and the mixture was stirred at 60° C. for 2 hours. After completion of the reaction, ether (100 ml) was added, and the mixture was extracted with brine (80 ml) twice, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The resulting crude product was purified by silica gel chromatography to give 2-(4-chlorobenzyloxy)-α-(1-imidazolyl)benzaldehyde O-benzyloxime (0.38 g) as colorless crystals. mp. 94°-95.5° C.
