Procedure

The title compound (131 mg) was prepared according to Example 193 using 205 mg of 2-ethyl-3-trifluoromethanesulfonyloxy-4,5,7,8-tetrahydro-2H-1,2,6-triaza-azulene-6-carboxylic acid tert-butyl ester (Example 193, Step A) and 245 mg of 4-isopropylphenylboronic acid. MS (ESI): exact mass calculated for C18H25N3, 283.20; found, m/z 284.5 [M+H]+. 1H NMR (500 MHz, CD3OD): 7.48-7.46 (m, 2H), 7.34-7.33 (m, 2H), 4.12 (q, J=7.3 Hz, 2H), 3.50-3.45 (m, 2H), 3.36-3.33 (m, 2H), 3.27-3.25 (m, 2H), 3.01 (m, 1H), 2.87-2.85 (m, 2H), 1.34 (t, J=7.3 Hz, 3H), 1.31 (d, J=6.9 Hz, 6H).
