Chlorotrimethylsilane → N-(4-(piperazin-1-yl)phenyl)-4-(piperidin-1-yl)-7H-pyrrolo[2,3-d]pyrimidin-2-amine

Participants

Reaction Steps

A mixture of 2-chloro-4-(piperidin-1-yl)-7H-pyrrolo[2,3-d]pyrimidine (123 mg, 0.520 mmol), 1-(4-(4-aminophenyl)piperazin-1-yl)ethanone (200 mg, 0.913 mmol) and trimethylsilyl chloride (0.200 mL, 1.58 mmol) in n-BuOH (5 mL) was stirred at 120° C. for 20 h. n-BuOH was removed in vacuo. The residue was purified by HPLC to give N-(4-(piperazin-1-yl)phenyl)-4-(piperidin-1-yl)-7H-pyrrolo[2,3-d]pyrimidin-2-amine (5 mg) (MS 378.5 (M+H)) and 1-(4-(4-(4-(piperidin-1-yl)-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino)phenyl)piperazin-1-yl)ethanone (31 mg) (MS 420.5 (M+H); UV 205.8, 275.8 nm).
