Procedure

The title compound (70.0 mg) was prepared from 207.0 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 98.5 mg of 4-fluorophenylboronic acid as in Example 199. MS (ESI): exact mass calculated for C19H18FN3, 307.15; found, m/z 308.2 [M+H]+. 1H NMR (500 MHz, CDCl3): 7.28-7.24 (m, 2H), 7.22-7.16 (m, 3H), 7.13-7.10 (m, 2H), 7.05-7.01 (m, 2H), 3.12-3.08 (m, 2H), 3.05-3.02 (m, 2H), 3.01-2.98 (m, 2H), 2.68-2.64 (m, 2H).
