Procedure

The title compound (91 mg) was prepared according to Example 281 using 200 mg of 2-cyclopropyl-3-trifluoromethanesulfonyloxy-4,5,7,8-tetrahydro-2H-1,2,6-triaza-azulene-6-carboxylic acid tert-butyl ester (Example 281, Step C) and 97 mg of 4-cyanophenylboronic acid. MS (ESI): exact mass calculated for C17H18N4, 278.15; found, m/z 279.4 [M+H]+. 1H NMR (500 MHz, CD3OD): 7.94-7.92 (m, 2H), 7.71-7.70 (m, 2H), 4.66 (br s, 1H), 3.71-3.68 (m, 1H), 3.47 (br s, 1H), 3.39-3.19 (m, 4H), 3.01-2.88 (m, 2H), 0.96-0.90 (m, 4H).
