To a solution of 2-(2-chloro-4-morpholinothieno[3,2-d]pyrimidin-6-yl)propan-2-amine (150 mg, 0.5 mmol) in CH2Cl2 (10 mL) was added Et3N (230 μL, 1.6 mmol) and the HCl salt of p-anisoyl chloride (160 mg, 0.9 mmol). The resulting mixture stirred at room temperature overnight. The reaction was quenched by the addition of saturated aqueous NaHCO3. The organic layer was separated and the aqueous layer was extracted with EtOAc. The combined organic layers were dried over Na2SO4, filtered, and concentrated in vacuo. A portion (0.2 mmol) of the resulting crude material was utilized in a Suzuki coupling using General Procedure A with 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indazole 7 to provide 412 after reverse phase HPLC purification (30 mg).
