Procedure

To a solution of 6-bromomethyl-2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidine (100 mg, 0.29 mmol) in DMF (3 mL) were added (R)-2-isopropyl-piperazine-1-carboxylic acid tert-butyl ester hydrochloride (87 mg, 0.33 mmol) and potassium carbonate (124 mg, 0.90 mmol). The resulting mixture was stirred at RT for 18 h, then diluted with water and DCM. The organic layer was separated, dried (Na2SO4) and concentrated in vacuo. The resultant residue was purified by column chromatography to give the title compound as a white solid (139 mg, 97%).
