Procedure

The title compound (134 mg) was prepared as in Example 177, Steps C and D, using 202 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 212 mg of 4-ethylphenylboronic acid. MS (ESI): exact mass calculated for C18H25N3, 283.20; found, m/z 284.5 [M+H]+. 1H NMR (500 MHz, CD3OD): 7.44 (d, J=7.7 Hz, 2H), 7.31 (d, J=7.7 Hz, 2H), 4.52 (m, 1H), 3.50-3.48 (m, 2H), 3.36-3.34 (m, 2H), 2.85-2.83 (m, 2H), 2.75 (q, J=7.7 Hz, 2H), 1.47 (d, J=6.6 Hz, 6H), 1.29 (t, J=7.7 Hz, 3H).
