Reaction Steps

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.
