実験手順

A solution of 3-(4-[2-(5-methyl-2-phenyl-oxazol-4-yl)-ethoxy]-2-{[methyl-(2,2,2-trifluoro-acetyl)-amino]-methyl}-phenyl)-propionic acid tert-butyl ester (111 mg, 0.20 mmol) in methanol (5 mL) and THF (5 mL) was treated with 2N NaOH (1.0 mL, 2.0 mmol) and heated at 55° C. for 1 h. The reaction mixture was cooled, concentrated, neutralized with 1N HCl and extracted into EtOAc. The organic layer was washed with saturated NaHCO3 solution and brine, dried (Na2SO4), and concentrated. The residue was purified by silica gel radial chromatography (CH2Cl2/methanol 95/5 to 90/10) to the title compound (37 mg, 42%). MS (ES) m/z 451.3 [M+1].
