Reaction Steps

A mixture of 86 mg of the above-synthesized methyl 5-(1H-imidazo[4,5-c]pyridin-1-yl)-3-{1-[2-(trifluoromethyl)phenyl]ethoxy}thiophene-2-carboxylate and 10 ml of a saturated solution of ammonia in methanol was stirred in a microwave vial at 125° C. for 4 h in the microwave cavity. The reaction mixture was allowed to cool down to room temperature, then another 10 ml of a saturated solution of ammonia in methanol were added and the procedure was repeated as described above. The solvent was removed under vacuum and the residue was purified by flash chromatography to give the title compound.
