实验过程

To a solution of 3-Phenyl-2-[(4-phenyl-thiazol-2-yl)-hydrazono]-propionic acid (4b) (1.0 mmol, 337 mg) in DME (5 mL) at −15° C., were added NMM (1.1 mmol, 121 μL), then IBCF (1.1 mmol, 147 μL). Then, a solution of NH4OH concentrated was added and the mixture was stirred for 20 minutes. 5 mL of water was added and the precipitate was filtered and washed with H2O and hexane to give the desired product.
