Procedure

1-({4-[(2-Fluoro-4-iodophenyl)amino]-3-thienyl}carbonyl)-3-(hydroxymethyl)azetidin-3-ol (247 mg, 0.551 mmol), was suspended in dichloromethane (10 mL) and treated with 4-(dimethylamino)pyridine (80 mg, 0.661 mmol), and 2,4,6-triisopropylbenzenesulfonyl chloride (183 mg, 0.604 mmol) at ambient for 15 h. The mixture was adsorbed on to silica and purified by column chromatography (silica gel, 30% ethyl acetate in hexanes) to give [1-({4-[(2-fluoro-4-iodophenyl)amino]-3-thienyl}carbonyl)-3-hydroxyazetidin-3-yl]methyl 2,4,6-tris(1-methylethyl)benzenesulfonate (101 mg, 0.141 mmol, 26% yield): MS (EI) for C30H36FIN2O5S2: 715 (MH+).
