Procedure
A solution of 4,4,4-trifluorocrotonic acid (300 mg, 1.90 mmole), t-butylaniline (371 μL, 2.28 mmole), 1-(3-dimethylamino-propyl)-3-ethylcarbodiimide hydrochloride (510 mg, 2.66 mmole) and DMAP (8 mg) in CH2Cl2 (5 mL) was stirred at room temperature for 18 hrs. The mixture was diluted with CH2Cl2, washed with 1N NaOH, water, 1N HCl, 10% NaHCO3 and dried (MgSO4). Evaporation in vacuo to gave the title compound as a white solid. NMR (CDCl3): δ 1.33 (s, 9H); 6.63 (d, 1H); 6.90 (dq, 1H); 7.37 (s, 1H); 7.39 (d, 2H); 7.51 (d, 2H).
