A mixture of (6Z)-5H-dipyrido[2,3-b:4′,3′-f]azepine-5,6(11H)-dione 6-oxime (930 mg, 3.9 mmol), ammonium acetate (5.58 g, 72.4 mmol) and 5-methyl-1-(tetrahydro-2H-pyran-2-yl)-3-(trifluoromethyl)-1H-pyrazole-4-carbaldehyde (2.03 g, 7.74 mmol) in acetic acid (5.6 mL) was stirred at 80° C. for 2 h. The reaction was cooled to ambient temperature and partitioned between water and 3:1 CHCl3:isopropanol. The phases were separated and the aqueous phase was washed with additional solvent. The combined organic phase was washed with water, sat'd NaHCO3, then sat'd NaCl, dried over MgSO4 and reduced to dryness in vacuo to leave 2-[5-methyl-1-(tetrahydro-2H-pyran-2-yl)-3-(trifluoromethyl)-1H-pyrazol-4-yl]imidazo[4,5-d]dipyrido[2,3-b:4′,3′-f]azepin-3(8H)-ol, which was used without further purification. MS (EI) m/z=484.2 (M+H).
