Reaction Steps

The title compound (0.056 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 1-bromo-2-cyclohexylethane (0.053 mL) in place of benzyl chloride. The reaction sequence also yielded 3-(4-chloro-phenyl)-2-(2-cyclohexyl-ethyl)-4,5,7,8-tetrahydro-2H-1,2,6-triaza-azulene-6-carboxylic acid tert-butyl ester in the alkylation step.
