Reaction Steps

3-{[2-(2-Trifluoromethyl-biphenyl-4-yl)-benzothiazol-6-ylmethyl]-amino}-propionic acid tert-butyl ester (31 mg, 0.0605 mmol) is dissolved in TFA/CH2Cl2 (1/1) (1 mL). The solution is stirred at room temperature for an hour. The mixture is concentrated and purified by reversed phase preparative LC/MS to give 10 mg of 3-{[2-(2-trifluoromethyl-biphenyl-4-yl)-benzothiazol-6-ylmethyl]-amino}-propionic acid: 1H NMR (CD3OD, 400 MHz) δ 8.54 (s, 1H), 8.35 (d, 1H), 8.22 (s, 1H), 8.18 (d, 2H), 7.68 (d, 1H), 7.45 (m, 3H), 7.37 (m, 2H), 4.44 (s, 2H), 3.36 (m, 2H), 2.80 (m, 2H); MS (ES+) 457.0 (M+H+).
