Acetonitrile → 3-(5-morpholin-4-ylpyridin-3-yl)-3-[4-(7-[2-(trimethylsilyl)-ethoxy]methyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]propanenitrile

Participants

Reaction Steps

To a solution of 4-(1H-pyrazol-4-yl)-7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]-pyrimidine (120 mg, 0.00038 mol) in ACN (10 mL, 0.2 mol) and (2E)-3-(5-morpholin-4-ylpyridin-3-yl)acrylonitrile (70 mg, 0.0003 mol) (mixture of isomers), DBU (50 μL, 0.0003 mol) was added and the resulting mixture was stirred overnight. The mixture was partitioned between water and ethyl acetate. The combined organic layers were washed with saturated sodium chloride, dried over magnesium sulfate, filtered and concentrated to give 3-(5-morpholin-4-ylpyridin-3-yl)-3-[4-(7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]propanenitrile (200 mg, 100%) as a crude product; L/MS=531 (M+1).
