Reaction Conditions

Reaction Steps

A solution of sulfurylchloride (0.92 ml, 11.0 mmol, 1.16 equiv) in DCM (20 mL) is added dropwise (30 min) to a cold (−15° C.) solution of (2-iodo-3,5-dimethoxy-phenyl)-carbamic acid tert-butyl ester (3.6 g, 9.49 mmol) in THF (48 ml), under an argon atmosphere. The reaction mixture is allowed to stir for 1 h at −15° C. and then poured onto a mixture of ice/H2O (100 mL), a saturated aqueous solution of NaHCO3 (80 ml), and EtOAc (100 mL). The layers are separated and the aqueous phase is extracted with EtOAc (2×100 mL). The combined organic phase is washed with H2O (3×60 mL) and brine (60 mL), dried (Na2SO4), filtered and concentrated. The residue is purified by silica gel column chromatography (DCM) followed by crystallization from DCM/Hex to afford the title compound. ESI-MS: 411.9, 413.9 [M-H]−, TLC: Rf=0.18 (DCM/Hex, 7:3).
