Reaction Steps

A solution of 8-methyl-1,3,8-triaza-spiro[4.5]decane-2,4-dione (40 mg) in DMF (0.6 mL) was added to a solution of 2-(4-(4-cyano-1-methyl-1H-imidazo[4,5-e]pyridin-6-yl)-2-(trifluoromethyl)phenoxy)ethyl methanesulfonate (50 mg) in DMF (0.4 mL), K2CO3 (41 mg) and tetrabutyl ammonium iodide (TBAI, 26 mg). The mixture was stirred at 90° C. for 14 hours. The crude mixture was directly purified by preparative HPLC (HPLC:column XBridge MS C18 30×100 mm, 5 μm, Eluent:A:NH4HCO3, 10 mmol, pH=9.5/B:Acetonitrile, Focused gradient/8 minutes/50 mL/min) to afford 1-methyl-6-{4-[2-(8-methyl-2,4-dioxo-1,3,8-triaza-spiro[4.5]dec-3-yl)-ethoxy]-3-(trifluoromethyl)-phenyl}-1H-imidazo[4,5-c]pyridine-4-carbonitrile (20 mg).
