Reaction Steps

0.5 g 2,3-Diamino-6-methyl pyridine (4.0 mmol) and 0.37 g glycolic acid were heated at 150° C. for 1 h. The residue was suspended in chloroform (7.0 ml) treated with 1.5 ml thionyl chloride (20 mmol)for 4 h at reflux. The mixture was evaporated and the residue triturated with methanol. After concentration the residue was stirred over night in ether and the suspension was then filtered. The residue on the filter was dried to yield 0.67 g 2-chloromethyl-5-methyl-3H-imidazo[4,5-b]pyridine hydrochloride as a dark brown solid; M.p.: 225–230° C., (dec.).
