Iodine chloride → HCID 490382, compound

Iodine monochloride (92 mg, 0.56 mmol) was added slowly during a five minute period to a suspension of sodium azide (129 mg, 2.0 mmol) in dry acetonitrile (10 ml) at ice-bath temperature with stirring. This mixture was stirred for a further 5 min., a solution of 1 (105 mg, 0.49 mmol) in dry acetonitrile (15 ml) was added, the reaction mixture was stirred at 0° C. for 30 min. The resulting red-brown colored reaction mixture was poured onto ice cold water (25 ml), the mixture was extracted with ethyl acetate (3×50 ml) and the ethyl acetate extract was washed with 5% aqueous sodium thiosulfate (50 ml). Drying the colorless ethyl acetate fraction Na2SO4), removal of the solvent in vacuo and purification of the residue obtained by elution from a silica gel column using chloroform:methanol (93:7, v/v) as eluent afforded 2c (65 mg, 34%) as a viscous oil.
