反应详情

In a 15 mL round-bottomed flask, 7-tosyl-7H-pyrrolo[2,3-d]pyrimidine-5-carbonitrile (1 g, 3.35 mmol, Eq: 1.00) and TBAF (13.4 ml, 13.4 mmol, Eq: 4.00) were combined with Tetrahydrofuran to give an off-white solution. The reaction mixture was stirred for 3 h. The reaction mixture was poured into 20 mL sat NH4Cl and extracted with EtOAc (3×25 mL). The organic layers were dried over MgSO4 and concentrated in vacuo. The crude material was triturated with diethyl ether (1×20 mL) to obtain 7H-pyrrolo[2,3-d]pyrimidine-5-carbonitrile (312 mg, 65%).
