Procedure

The title compound (45.2 mg) was prepared as in Example 177, Steps C and D, using 269.2 mg of 2-cyclopentyl-3-trifluoromethanesulfonyloxy-4,5,7,8-tetrahydro-2H-1,2,6-triaza-azulene-6-carboxylic acid tert-butyl ester (Example 180, Step A) and 359.2 mg of 4-trifluoromethylphenylboronic acid. MS (ESI): exact mass calculated for C19H22F3N3, 349.49; found, m/z 350.3 [M+H]+. 1H NMR (500 MHz, CD3OD): 7.87 (d, J=7.9 Hz, 2H), 7.55 (d, J=7.9 Hz, 2H), 4.48 (m, 1H), 3.43-3.40 (m, 2H), 3.21-3.17 (m, 2H), 2.81-2.77 (m, 2H), 2.07-1.86 (m, 6H), 1.66-1.57 (m, 2H).
