Versuchsvorschrift

Following the procedure of Example 15b, 5,7-dichloro-3H-imidazo[4,5-b]pyridine (J. Med. Chem., 2007, 50, 828-834) (0.118 g, 0.624 mmol) was reacted with 2-iodopropane. The crude product mixture was purified by silica gel chromatography (25 to 35% ethyl acetate in hexane eluant) to afford a mixture of the title compound (major) and an isomeric product as a solid. MS m/z 230.2 (M+1).
