Reaction Steps

To a solution of ethyl 4-amino-5-iodo-2-(methylthio)benzoate (13.6 g, 40 mmol) in DCM (100 mL) was added Et3N (13.8 mL, 100 mmol), followed by MsCl (7.7 mL, 100 mmol) at 0° C. After addition the mixture was stirred at rt for 2 h. 1N HCl solution (50 mL) was added to the mixture and the aqueous phase was extracted with DCM (1×100 mL). The organic solution was washed with brine, dried over anhydrous Na2SO4, filtered and concentrated in vacuo to give ethyl 5-iodo-4-(N-(methylsulfonyl)methylsulfonamido)-2-(methylthio)benzoate.
