Participants

Reaction Steps

To a solution of (5-{1-[4-(tert-butyl-dimethyl-silanyloxy)-3-methyl-phenyl]-1-ethyl-propyl}-3-methyl-thiophen-2-yl)-methanol (1.0 g, 2.39 mmol) in Et2O (5 ml) is added triethyl amine (666 μl, 4.78 mmol). The mixture is added to a solution of p-toluenesulfonyl chloride (501 mg, 2.62 mmol) in Et2O (5 ml) and stirred overnight. The reaction is filtered, concentrated and chromatographed (12 g SiO2, 5% EtOAc/Hex) to yield the title compound (740 mg, 55%).
