Participants

Reaction Steps

To a solution of 3-(3-chlorosulfonyl-4-methoxy-phenyl)-3-phenyl-propionic acid methyl ester (500 mg, 1.36 mmol) in DCM (50 mL) is added triethylamine (0.57 ml, 4.08 mmol) and guanidine hydrochloride (0.14 g, 1.50 mmol). The reaction mixture is stirred at RT overnight, then diluted with DCM (100 mL). The reaction mixture is washed with an aqueous saturated solution of NaHCO3 (30 mL), water (30 mL) then brine (30 mL). The organic phase is then dried over MgSO4, filtered and concentrated in vacuo. Purification of the residue by reverse phase chromatography (Isolute™ C18, 0-100% acetonitrile in water with 0.1% TFA) affords the title compound.
