Procedure

To a mixture of t-butyl (4-{1-[4-(3,3-dimethyl-2-oxobutoxy)-3-methylphenyl]-1-ethylpropyl}-2-methylbenzyl)-(2-methanesulfonylethyl)carbamate (0.25, g, 0.41 mmol) and CH2Cl2 (5 mL) is added TFA (5 mL,), stirred for 10 m, and concentrated. The residue is diluted with EtOAc (100 mL), washed with sat.d NaHCO3 (2×30 mL); MgSO4 dried, and chromatographed (90% EtOAc) to give the title compound (0.19 g, 0.39 mmol, 95%).
