Procedure

Alternatively, racemic 4-(5-chloropyridin-3-yl)-3-[1-(trans-4-methylcyclohexyl)ethyl]-3H-imidazo[4,5-c]pyridine-6-carbonitrile (Step 2) was resolved into its enantiomers as described in Preparative Example 15.1 and brominated using the conditions described above or using the alternative conditions (disodium hydrogen phosphate and 1,3-dibromo-5,5-dimethylhydantoin in THF at 35° C., described in Example 2.1, Step 1 and Preparative Example 3.1, Step 3) to afford 2-bromo-4-(5-chloropyridin-3-yl)-3-[(1S)-1-(trans-4-methylcyclohexyl)ethyl]-3H-imidazo[4,5-c]pyridine-6-carbonitrile and 2-bromo-4-(5-chloropyridin-3-yl)-3-[(1R)-1-(trans-4-methylcyclohexyl)ethyl]-3H-imidazo[4,5-c]pyridine-6-carbonitrile.
