Procedure
To a stirring suspension (2-chloro-7-methyl-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-yl)-methanol in toluene at 40° C. was added PBr3 and the reaction mixture stirred at 100° C. overnight. DCM/saturated aqueous NaHCO3 extraction of the cooled mixture gave 6-bromomethyl-2-chloro-7-methyl-4-morpholin-4-yl-thieno[3,2-d]pyrimidine.
