실험 절차

To a solution of 4-(1H-pyrazol-4-yl)-7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]-pyrimidine (0.216 g, 0.684 mmol) in ACN (4 mL, 0.08 mol) was added crude senecionitrile (0.111 g, 1.37 mmol), followed by DBU (200 mL, 0.002 mol) and the resulting mixture was heated to 60° C. for 23 hours. The mixture was cooled to room temperature and the ACN was evaporated. The mixture was diluted with ethyl acetate and washed with dilute HCl and brine. The organic solution was dried over sodium sulfate, filtered and concentrated. Purification by silica gel chromatography (ethyl acetate/hexanes) afforded the desired product.
