Procedure

The title compound (129 mg) was prepared as in Example 177, Steps C and D, using 204 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 194 mg of 4-methylphenylboronic acid. MS (ESI): exact mass calculated for C17H23N3, 269.19; found, m/z 270.5 [M+H]+. 1H NMR (500 MHz, CD3OD): 7.28 (d, J=7.7 Hz, 2H), 7.12 (d, J=7.7 Hz, 2H), 4.32 (m, 1H), 3.34-3.33 (m, 2H), 3.12-3.10 (m, 2H), 2.70-2.68 (m, 2H), 2.33 (s, 3H), 1.30 (d, J=6.6 Hz, 6H).
