Participants

Reaction Steps

To a solution of 6-(4-methanesulfonyl-piperazin-1-ylmethyl)-2-methylsulfanyl-4-morpholin-4-yl-thieno[2,3-d]pyrimidine (90 mg) in 1,2-dimethoxyethane (10 mL) was added 6-tributylstannanyl-3-(2-trimethylsilanyl-ethoxymethyl)-3H-imidazo[4,5-]pyridine (219 mg) and copper(I)bromide-dimethylsulfide (84 mg) and the reaction stirred at room temperature for 10 min. Then, tetrakis(triphenylphosphine)palladium (0) (12 mg) was added and the reaction heated at reflux for 16 h. After cooling to room temperature, the reaction mixture was diluted with ethyl acetate (20 mL) and washed with water (2×30 mL), aqueous brine solution (2×20 mL), dried (MgSO4), reduced in vacuo and purified by column chromatography to give 6-(4-methanesulfonyl-piperazin-1-ylmethyl)-4-morpholin-4-yl-2-[3-(2-trimethylsilanyl-ethoxymethyl)-3H-imidazo[4,5-b]pyridin-6-yl]-thieno[2,3-d]pyrimidine as a white solid.
