Procedure

To a mixture of 6-bromomethyl-2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidine (380 mg) and (3S,5R)-1-methanesulfonyl-3,5-dimethyl-piperazine (314 mg) in acetonitrile (10 mL) was added potassium carbonate (620 mg). The reaction mixture was heated at 80° C. for 16 h and then allowed to cool to room temperature. The reaction mixture was then partitioned between dichloromethane (20 mL) and saturated aqueous sodium bicarbonate solution (20 mL). The combined organics were washed with brine (30 mL), dried (MgSO4), reduced in vacuo and purified by column chromatography to give 2-chloro-6-((2S,6R)-4-methanesulfonyl-2,6-dimethyl-piperazin-1-ylmethyl)-4-morpholin-4-yl-thieno[3,2-d]pyrimidine.
