실험 절차

A solution of methyl (2E)-3-phenylacrylate (500 mg, 0.003 mol) in ACN (2 mL, 0.04 mol) was slowly added to a solution of 4-(1H-pyrazol-4-yl)-7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]pyrimidine (0.5 g, 0.002 mol) in ACN (2 mL, 0.04 mol) and DBU (500 mL, 0.003 mol). The reaction was stirred at room temperature over the weekend. The reaction was partitioned between water and EtOAc. The organic layer was washed with saturated sodium chloride, dried over MgSO4, filtered and concentrated to give an oil. The product was purified by FCC on silica gel using EtOAc/Hexane (1:2 to 1:1) gave methyl 3-phenyl-3-[4-(7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]propanoate (500 mg, 70%) as a semisolid residue.
