Participants

Reaction Steps

The title compound (47 mg) 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; 0.30 mmol) using chloro-cyclooctane (1.0 mmol) in place of chloro-cyclobutane according to Example 238. The reaction sequence also yielded 3-(4-chloro-phenyl)-2-cyclooctyl-1,4,5,6,7,8-hexahydro-1,2,6-triaza-azulene-6-carboxylic acid tert-butyl ester in the alkylation step.
