2-(2-Chloro-4-morpholinothieno[2,3-d]pyrimidin-6-yl)propan-2-ol (100 mg) was reacted with 161 mg of 3-((2-(trimethylsilyl)ethoxy)methyl)-2-methyl-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3H-imidazo[4,5-b]pyridine 54 via Example 6b and General Procedure A. Crude 2-(2-(1-((2-(trimethylsilyl)ethoxy)methyl)-2-methyl-1H-benzo[d]imidazol-6-yl)-4-morpholinothieno[2,3-d]pyrimidin-6-yl)propan-2-ol was then refluxed overnight with 2 equivalents of tetrabutylammoniumfluoride in THF to remove the SEM protecting group. The crude material was then extracted with water and ethyl acetate. The organic layer was concentrated to dryness and then purified via reverse phase HPLC to give 5.1 mg of 414. MS (Q1) 411.2 (M)+
