Reaktionsschritte

To a solution of 4-(5-chlorothiazolo[5,4-d]pyrimidin-7-yl)morpholine 14 dissolved in THF at −78° C. was added 1.6M solution of n-butyllithium in hexanes). The reaction mixture was stirred at −78° C. for 30 minutes. A solution of iodine in THF was added and reaction mixture was allowed to slowly warm up to room temperature and stirred for 45 minutes. The reaction mixture was quenched with saturated aq. Na2S2O3, and extracted with dichloromethane. The combined organic layers were dried (Na2SO4) and concentrated. The crude reaction mixture was purified by flash chromatography to yield 4-(5-chloro-2-iodothiazolo[5,4-d]pyrimidin-7-yl)morpholine 18.
