Procedure

Using the general procedure for the alkylation of secondary amines with LiN(TMS)2 described in Step A of Example 29, 3-[4-(N-(1-carbomethoxy -1-phenylmethyl)amino)phenylmethyl]-5,7-dimethyl-2-ethyl-3H-imidazo[4,5-b]pyridine (Step A, Example 28) was alkylated with isopropyl bromide. Standard workup and purification by flash chromatography afforded the title compound.
