Procedure
The title compound (43.6 mg) was prepared from 198.3 mg of 2-phenyl-3-trifluoromethanesulfonyloxy-4,5,7,8-tetrahydro-2H-1,2,6-triaza-azulene-6-carboxylic acid tert-butyl ester (Example 176, Step B) and 94.7 mg of 4-methoxyphenylboronic acid as described in Example 199. MS (ESI): exact mass calculated for C20H21N3O, 319.17; found, m/z 320.2 [M+H]+. 1H NMR (500 MHz, CDCl3): 7.28-7.24 (m, 2H), 7.21-7.17 (m, 3H), 7.07 (d, J=8.8 Hz, 2H), 6.87 (d, J=8.8 Hz, 2H), 3.81 (s, 3H), 3.11-3.08 (m, 2H), 3.04-3.01 (m, 2H), 3.00-2.97 (m, 2H), 2.68-2.65 (m, 2H).
