Reaction Steps

To a solution of crude 3-{6-[3-(2-trifluoromethyl-biphenyl-4-yl)-[1,2,4]oxadiazol-5-yl]-3,4-dihydro-1H-isoquinolin-2-yl}-propionic acid tert-butyl ester in CH2Cl2 (1 mL) is added TFA(1 mL). The mixture is stirred at room temperature for an hour. All the solvents are evaporated. The mixture is purified by reverse phase preparative LC/MS to give 3-{6-[3-(2-Trifluoromethyl-biphenyl-4-yl)-[1,2,4]oxadiazol-5-yl]-3,4-dihydro-1H-isoquinolin-2-yl}-propionic acid: 1H NMR (DMSO, 400 MHz) δ 8.52 (s, 1H), 8.38 (d, 1H), 8.15 (s, 1H), 8.10 (d, 1H), 7.68 (d, 1H), 7.50 (m, 4H), 7.38 (m, 2H), 3.20-3.50 (m, 8H), 2.92 (t, 2H), MS (ES+): (494.10, M+1)+.
