Procedure

To a solution of 6-bromomethyl-2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidine (85 mg, 0.244 mmol) in DMF (2 mL) were added water (13 μL), methyl-piperidin-4-yl-carbamic acid tert-butyl ester (105 mg, 0.489 mmol) and cesium carbonate (159 mg, 0.489 mmol). The resulting mixture was stirred at RT for 18 h. The reaction mixture was loaded onto an Isolute® SCX-2 cartridge, washed with MeOH then eluted with 2 M NH3 in MeOH. The resultant residue was purified by column chromatography to give the title compound as a pale brown solid (73 mg, 62%).
