Reaction Steps

N-{4-{2-[4-(Hydroxymethyl)phenyl]ethyl}-5-[4-(methylsulfonyl)phenyl]-1,3-thiazol-2-yl}acetamide (100 mg), N-hydroxyphthalimide (39.8 mg), triphenylphosphine (64 mg) and tetrahydrofuran (2 ml) were combined under nitrogen atmosphere, then, diethyl azodicarboxylate (40 wt % solution in toluene) (0.111 ml) was added to the solution at 0° C., and the mixture was stirred at 20° C. for 5 hrs. The reaction mixture was poured into saturated sodium hydrogen carbonate aqueous solution, and extracted with chloroform. The organic layer was washed with brine, dried over magnesium sulfate, filtered and evaporated. The crude material was purified by preparative thin-layer chromatography over silica gel with chloroform/methanol (30:1) as an eluent to give N-{4-[2-(4-{[(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)oxy]methyl}phenyl)ethyl]-5-[4-(methylsulfonyl)phenyl]-1,3-thiazol-2-yl}acetamide as a yellow foam.
