Reaction Steps

To a solution of (R)-6,6-Bis-(4-fluoro-phenyl)-hexanoic acid methyl-pyrrolidin-3-yl-amide (0.78 g, 2.02 mmol) in dry CH2Cl2 (30 ml) was added 3,5-di-tert-butyl-4-methoxy benzoic acid (0.53 g, 2.02 mmol) under nitrogen. To the reaction was added EDC (0.77 g, 4.04 mmol) and DMAP (cat) and the reaction mixture stirred under nitrogen at room temperature overnight. The reaction was then concentrated under reduced pressure. The residue was dissolved in ethyl acetate: water (10:1) (150 ml). The organic was washed with water (30 ml, 2×) and 10% NaOH (30 ml) and dried over MgSO4 and evaporated to dryness. The resulting residue was purified by column chromatography using CH2Cl2:CH3OH (15:1) to give 1.1 g of desired product.
