Procedure

To the solution of 3-{4-[1-(2-formyl-4′-isopropyl-biphenyl-4-yloxy)-3-methyl-butyl]-benzoylamino}-propionic acid (240 mg, 0.48 mmol) and Morpholine (84 mg, 0.96 mmol) in dichloromethane (20 ml) is added NaBH(OAc)3 (143 mg, 0.67 mmol) and acetic acid (58 mg, 0.96 mmol). The resulting mixture is stirred overnight, diluted with ethyl acetate, washed with 1N HCl, water, brine, dried over MgSO4, and concentrated. The residue is purified by column chromatography to afford 80 mg of the titled compound as a white solid. MS (ES): 573.5 [M+H]+.
