実験手順

An aliquot of 5-(1-{4-[2-(tert-butyl-dimethyl-silanyloxy)-3,3-dimethyl-butoxy]-3-methyl-phenyl}-1-ethyl-propyl)-3-methyl-thiophene-2-sulfonyl chloride (step D) (4 ml, 1.5 mmol) is added to a suspension of glycine methyl ester hydrochloride (565 mg, 4.5 mmol) and Et3N (0.94 ml, 6.75 mmol) in dichloromethane (10 ml) at 0° C. It is stirred at RT overnight, concentrated, and partitioned between EtOAc and 1N HCl. The organic layer is concentrated and chromatographed (Hex to 20% EtOAc/Hex) to give the title product (380 mg, 40%).
