In a different strategy, reductive alkylation of 2,3-diaminopyridine (V) with aldehyde (VI) using borane-pyridine complex yielded regioselectively the 3-alkylamino pyridine (VII). Subsequent cyclization of (VII) with triethyl orthoformate afforded the desired imidazopyridine (III). In an alternative, more direct procedure, the bicyclic compound (III) was obtained by reductive condensation of the 2-formamido derivative (VIII) with aldehyde (VI) in the presence of borane-pyridine complex.
