Versuchsvorschrift

2-(2-Triphenylmethylamino-4-thiazolyl)-2-(Z-hydroxyimino)acetic acid (10 g) was suspended in 140 ml of anhydrous dichloromethane, and 6.7 ml of triethylamine was added to this suspension under ice cooling with stirring. To the resulting solution was added a solution of benzoyl chloride (3.2 g) in dichloromethane (20 ml). The mixture was stirred at room temperature for one hour, the insoluble matters were filtered off, and the filtrate was washed twice with 20ml 1N hydrochloric acid and 30 ml of saturated sodium chloride solution each and dried over anhydrous sodium sulfate. The dried filtrate was concentrated under reduced pressure, and the brown viscous residue (12 g) was purified by silica gel column chromatography using chloroform containing 10 to 15% methanol as eluent, giving 3 g of the objective compound as light brown crystals.
