N-Iodosuccinimide → HCID 24773447, compound

Participants

Reaction Steps

5-(2,4-Bis-benzyloxy-5-isobutyl-phenyl)-isoxazole-3-carboxylic acid ethylamide (1 eq) and N-iodosuccinimide (2.0 eq), were dissolved in acetonitrile, ceric ammonium nitrate (0.1 eq) added and the solution was stirred at room temperature overnight. The reaction mixture was concentrated in vacuo and the resulting gum was partitioned between ethyl acetate and brine. The organic phase was dried over magnesium sulfate, filtered and concentrated in vacuo. The residue was purified by column chromatography, eluting with 4:1 hexane:ethyl acetate, to give 5-(2,4-bis-benzyloxy-5-isobutyl-phenyl)-4-iodo-isoxazole-3-carboxylic acid ethylamide as an oil.
