CDl (194.4 mg, 1.2 mmol) is added to the solution of 4-(2-hydroxyhexafluoroisopropyl) benzoic acid (288 mg, 1 mmol) in THF (10 mL) at room temperature. The reaction mixture is stirred for 10 minutes and N-methylphenethylamine (0.174 mL, 1.2 mmol) is introduced. The reaction mixture is then stirred for 14 hours. The solvent is removed and the residue is dissolved in EtOAc. The organic phase is washed with 1N HCl, saturated NaHCO3 and brine and dried over MgSO4. The product is obtained in pure form after removal of solvents (278.8 mg). 1H NMR (CD3OD, every peak appears as a pair) δ2.76 (t, 2H), 3.12 (s, 3H), 3.44 (t, 2H), 7.01 (d, 2H), 7.20 (d, 2H), 7.30 (m, 3H), 7.62 (d, 2H); ESIMS: m/z 406 (M+H).
