실험 절차

A solution of 2-[3-(difluoromethyl)-5-methyl-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazol-4-yl]imidazo[4,5-d]dipyrido[2,3-b:4′,3′-f]azepin-3 (8H)-ol (1.94 g, 4.17 mmol) in N,N-dimethylacetamide (30 mL, 0.3226 mol) was heated at 160° C. for 2.5 hours with triisopropyl phosphite (4.0 mL, 0.0174 mol). The reaction was allowed to cool and then poured into 50 mL water. The reaction was extracted with ethyl acetate and the organic extracts were washed with water, saturated NaCl, dried (MgSO4) and concentrated in vacuo. The reaction was chromatographed on silica gel using 3% Et3N with ethyl acetate, and 3% MeOH/ethyl acetate to give the desired product. 1H NMR (CDCl3): δ 9.52 and 9.45 (brs, 1H), 7.87-8.11 (m, 4H), 6.74-7.61 (m, 3H), 6.10 and 6.13 (br s, 1H), 5.40 (dd, 1H), 4.11 (m, 1H), 3.71 (m, 1H), 2.80 (s, 3H), 2.44 (m, 1H), 2.17 (m, 1H), 1.95 (m, 1H), 1.60-1.80 (m, 3H). Mass spec(EI) m/z=450 (M+1).
