Procedure
The title compound (103 mg) was prepared as in Example 177, Steps C and D, using 199 mg of 2-isopropyl-3-trifluoromethanesulfonyloxy-4,5,7,8-tetrahydro-2H-1,2,6-triaza-azulene-6-carboxylic acid tert-butyl ester (Example 189, Step A) and 265 mg of 4-trifluoromethylphenylboronic acid. MS (ESI): exact mass calculated for C17H20F3N3, 323.16. found, m/z 324.4 [M+H]+. 1H NMR (500 MHz, CD3OD): 7.86 (d, J=8.0 Hz, 2H), 7.55 (d, J=8.0 Hz, 2H), 4.34 (m, 1H), 3.43-3.40 (m, 2H), 3.20-3.18 (m, 2H), 2.80-2.78 (m, 2H), 1.40 (d, J=6.6 Hz, 6H).
