Procedure

The title compound (0.01 g) was prepared from 3-(4-chloro-phenyl)-4,5,7,8-tetrahydro-1H-1,2,6-triaza-azulene-6-carboxylic acid tert-butyl ester (Example 103, Step B; 0.4 mmol) using 2-chloromethyl-pyridine hydrogen chloride (0.5 mmol) in place of 2-chloromethyl-thiophene. The reaction sequence also yielded 3-(4-chloro-phenyl)-2-pyridin-2-ylmethyl-4,5,7,8-tetrahydro-2H-1,2,6-triaza-azulene-6-carboxylic acid tert-butyl ester in the alkylation step. MS (ESI): exact mass calculated for C19H19ClN4, 338.13; found, m/z 339.3 [M+H]+. 1H NMR (500 MHz, CDCl3): 8.49-8.48 (m, 1H), 7.56-7.54 (m, 1H), 7.44-7.42 (m, 2H), 7.32-7.30 (m, 2H), 7.19-7.11 (m, 1H), 6.84-6.82 (m, 1H), 5.39 (s, 2H), 2.93-2.87 (m, 4H), 2.76-2.74 (m, 4H).
