Participants

Reaction Steps

The title compound (0.006 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; 0.2 mmol) using 3,4,5-trimethoxybenzyl chloride (0.3 mmol) in place of 2-chloromethyl-thiophene. The reaction sequence also yielded 3-(4-chloro-phenyl)-2-(3,4,5-trimethoxy-benzyl)-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 C23H26ClN3O3, 427.17; found, m/z 428.1 [M+H]+. 1H NMR (500 MHz, CD3OD): 7.51-7.49 (m, 2H), 7.46-7.44 (m, 2H), 6.44 (s, 2H), 5.32 (s, 2H), 3.78 (s, 6H), 3.74 (s, 3H), 2.95-2.89 (m, 6H), 2.81-2.79 (m, 2H).
