Procedure

5-Chloro-2-(methylsulfonyl)-7-morpholinothiazolo[4,5-d]pyrimidine was reacted with 1-methylsulfonylpiperazine (HCl salt), using 2.8 equiv of triethylamine, via General Procedure C to give crude 5-chloro-2-(4-methylsulfonylpiperazin-1-yl)-7-morpholinothiazolo[4,5-d]pyrimidine, which was then reacted with 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrimidin-2-amine via General Procedure C again to give 135 after purification by reverse HPLC. MS (Q1) 478 (M+)
