Reaction Steps

The title compound (0.048 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 59, Step C, 0.1 g) using (2-chloroethyl)benzene (0.045 mL) in place of benzyl chloride. The reaction sequence also yielded 3-(4-chloro-phenyl)-2-phenethyl-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 C21H22ClN3, 351.15; found, m/z 352.2 [M+H]+. 1H NMR (500 MHz, CD3OD): 7.52-7.47 (m, 4H), 7.28-7.21 (m, 3H), 7.03-7.01 (m, 2H), 4.39 (t, J=6.4 Hz, 2H), 3.20-3.18 (m, 2H), 3.13-3.10 (m, 2H), 2.95-2.93 (m, 2H), 2.91-2.89 (m, 2H), 2.69-2.67 (m, 2H).
