Versuchsvorschrift
4-(5-Chloro-2-iodothiazolo[5,4-d]pyrimidin-7-yl)morpholine 18 was reacted with N-methylsulfonyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzenamine via General Procedure A to give crude 4-(5-chloro-7-morpholinothiazolo[5,4-d]pyrimidin-2-yl)-N-methylsulfonylbenzenamine, which was then reacted with 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrimidin-2-amine via General Procedure A again to give 125 after purification by reverse HPLC.
