Procedure

A mixture of Boc-4-azatryptamine (1.1 eq.) and 2,4-difluorobenzenesulfonyl chloride (1.0 eq.) in THF at room temperature is treated portionwise with solid potassium t-butoxide (1.2 eq), stirred at room temperature for 16 h, poured into saturated NaHCO3 and extracted with EtOAc. The combined extracts are dried over MgSO4 and concentrated in vacuo to give a residue. Purification of this residue by chromatography (silica gel, EtOAc/hexanes as eluent) affords the title carbamate compound.
