Reaction Steps

A mixture of 4-chloro-1,2-dimethyl-7-(4-morpholinylcarbonyl)-1H-pyrrolo[3,2-c]pyridine (68 mg), 3-chloroaniline (0.05 ml) and methanesulfonic acid (0.03 ml) in dry 1,4-dioxan was heated under microwave conditions at 180° C. for fifteen minutes. The reaction mixture was transferred to a round bottom flask and evaporated. The residue was partitioned between ethyl acetate (10 ml) and saturated sodium bicarbonate solution and washed with saturated sodium bicarbonate solution and water. The organic layer was dried (MgSO4) and evaporated to afford a brown oil. The oil was purified by Biotage chromatography on silica gel loading the column using dichloromethane and eluting with 5% ethyl acetate/hexane (200 ml) increasing the percentage of ethyl acetate to 20%, 50% and 100% to afford a white foam. The foam was dissolved in warm ethyl acetate and treated with 1M hydrochloric acid in diethyl ether. The mixture was evaporated, the residue triturated with diethyl ether to afford a white solid which was filtered off, washed with diethyl ether and dried to afford the title compound (59 mg).
