Using a procedure similar to that described in Example 1, except using 2-amino-2-methyl-3-(4,5,7-trichloro-2H-benzotriazol-2-yl)-propionitrile (35 mg, described in Example 39) and 4-(1,2,2,2-tetrafluoroethyl)benzoyl chloride, the title compound was isolated as a solid (6.2 mg, 11%). MS (ES): M/Z [M+H]=508. NMR: (400 MHz, CHLOROFORM-d): 1.90 (s, 3H), 5.20 (d, J=13.8 Hz, 1H), 5.53 (d, J=13.8 Hz, 1H), 5.69 (dq, J=44.3 Hz, 5.9 Hz, 1H), 7.54 (br.s, 1H), 7.58 (s, 1H), 7.60 (d, J=8.1 Hz, 2H) and 7.98 (d, J=8.2 Hz, 2H). 19F NMR (376 MHz, CHLOROFORM-d): −197.6-−197.1 (m, 1F), −79.0 (q, J=5.9 Hz, 3F).
