実験手順
To 4-hydrazino-1-[2-(trimethylsilyl)ethoxy]methyl-1H-pyrrolo[2,3-b]pyridine (0.083 g, 0.00030 mol) 3782-117-1 and 1,3-benzoxazol-2-ylmalonaldehyde (0.056 g, 0.00030 mol) in toluene (1.5 mL, 0.014 mol) was added molecular sieves. The mixture was heated in a sealed tube at 70° C. (an oil bath) with stilling for 2 h. The solvent was removed in vacuo and the crude product was purified by FCC on silica using ethyl acetate:hexanes 3:7 to give 2-[1-(1-[2-(trimethylsilyl)ethoxy]methyl-1H-pyrrolo[2,3-b]pyridin-4-yl)-1H-pyrazol-4-yl]-1,3-benzoxazole (0.090 gm) as an oil, LC/MS (M+H)+: 432.
