Procedure

The title compound (122 mg) was prepared according to Example 263 using 198 mg of 2-cyclobutyl-3-trifluoromethanesulfonyloxy-4,5,7,8-tetrahydro-2H-1,2,6-triaza-azulene-6-carboxylic acid tert-butyl ester (Example 276, Step A) and 88 mg of 4-fluorophenylboronic acid. MS (ESI): exact mass calculated for C17H20FN3, 285.16; found, m/z 286.4 [M+H]+. 1H NMR (500 MHz, CD3OD): 7.35-7.27 (m, 4H), 4.65-4.59 (m, 2H), 3.95-3.3.40 (m, 2H), 3.32-3.05 (m, 3H), 3.00-2.75 (m, 2H), 2.67-2.59 (m, 2H), 2.29-2.23 (m, 2H), 1.84-1.73 (m, 2H).
