Procedure

The title compound (17.5 mg) was prepared from 188.9 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 93.3 mg of p tolylboronic acid as in Example 199, using DME as the solvent. MS (ESI): exact mass calculated for C20H21N3, 303.17; found, m/z 304.2 [M+H]+. 1H NMR (500 MHz, CDCl3): 7.26-7.23 (m, 2H), 7.21-7.16 (m, 3H), 7.15-7.12 (m, 2H), 7.04-7.01 (m, 2H), 3.11-3.07 (m, 2H), 3.04-3.00 (m, 2H), 2.98-2.96 (m, 2H), 2.68-2.65 (m, 2H), 2.35 (s, 3H).
