Participants

Reaction Steps

A mixture of 4-chloro-7H-pyrrolo[2,3-d]pyrimidine (0.62 g, 4.1 mmol), 2-(chloromethyl)-1-phenyl-1H-benzo[d]imidazole (1.0 g, 4.1 mmol) and K2CO3 (0.6 g, 4.3 mmol) in DMSO (20 mL) was stirred at room temperature overnight. Then the mixture was added H2O (50 mL) and extracted with EtOAc (20 mL×3). The combine organic layers were concentrated in vacuo to give 4-chloro-7-(1-phenyl-1H-benzoimidazol-2-ylmethyl)-7H-pyrrolo[2,3-d]pyrimidine (1.2 g, yield 80%) as brown solid.
