Participants

Reaction Steps

To a solution of 1,1-dicyclohexyl-3-[4-(hydroxyimino-methyl)-thiazol-2-yl]-urea (0.15 mmol) in DCM (4 mL) was added methansulfonyl chloride (0.15 mmol) and DIEA (0.15 mL). The mixture was stirred at rt for 2 h and quenched with water (10 mL). The reaction mixture was extracted with ethyl acetate (3×10 mL). The combined organic extracts was washed with water (2×30 mL), dried over sodium sulfate, filtered and concentrated in vacuo. The crude product was purified by flash chromatography (silica, EtOAc/hexanes 1:4 to EtOAc/hexanes 1:1) to give the desired product in 30% yield.
