To a solution of methyl 3-[[5-[3-[[tert-butyl(dimethyl)silyl]oxymethyl]pyrrolidin-1-yl]-2-methyl-benzoyl]amino]-2,4-dimethyl-benzoate (0.35 g, 0.686 mmol) in THF (50 ml) is added Bu4NF 1.0 M in THF (0.537 g, 2.05 mmol) at 0° C. The reaction mixture is gradually warmed to ambient temperature. After 2 hours, the reaction mixture is diluted with ice-water and extracted twice with ethyl acetate. The organic layers are combined, dried over sodium sulfate, filtered, and concentrated under reduced pressure to give a residue. The residue is purified by flash chromatography (silica gel) over a gradient using 50% ethyl acetate in hexane to afford the title compound as a brown solid (150 mg, 51%).
