Procedure

The title compound (48 mg) was prepared as in Example 177, Steps C and D, using 129 mg of 2-cyclohexyl-3-trifluoromethanesulfonyloxy-4,5,7,8-tetrahydro-2H-1,2,6-triaza-azulene-6-carboxylic acid tert-butyl ester (Example 177, Step B) and 173 mg of 4-chlorophenylboronic acid. MS (ESI): exact mass calculated for C19H24ClN3, 329.17; found, m/z 330.1 [M+H]+. 1H NMR (500 MHz, CDCl3): 7.60-7.53 (m, 2H), 7.36-7.27 (m, 2H), 3.94-3.83 (m, 1H), 3.43-3.36 (m, 2H), 3.34-3.26 (m, 2H), 3.2-3.12 (m, 2H), 2.80-2.72 (m, 2H), 1.98-1.76 (m, 6H), 1.67 (br s, 1H), 1.32-1.17 (m, 3H).
