该中间体在本合成路线中的序号：(XXV)

The sodium carboxylate (XXII) is activated as the mixed anhydride (XXIII) by treatment with isobutyl chloroformate and triethylamine. Subsequent addition of diazomethane to the mixed anhydride (XXIII) leads to diazo ketone (XXIV), which is further transformed into bromo ketone (XXV) upon treatment with HBr. Cyclization of bromo ketone (XXV) with N-acetyl thiourea (XXVI) produces the thiazole derivative (XXVII). The methyl ester group of (XXVII) is finally hydrolyzed by means of LiOH to the target carboxylic acid.
