(S)-1-(1-Methyl-6-morpholino-1H-pyrrolo[3,2-b]pyridin-5-yl)ethanamine (200 mg, 0.768 mmol) was dissolved in THF (5 mL) along with 4,6-dichloro-2-(methylthio)pyrimidine-5-carbonitrile (169 mg, 0.768 mmol) and Et3N (0.118 mL, 0.845 mmol) to give an orange suspension. The reaction mixture was stirred at room temperature for 2 h, then diluted with ethyl acetate and washed saturated aq NH4Cl (3×15 mL). The combined organic layers were dried over MgSO4, filtered, and concentrated in vacuo. The crude product was then loaded onto an ISCO® silica gel cartridge (12 g) and eluted using an EtOAc/Hexane gradient. The product was collected and concentrated in vacuo to afford the title compound as a white solid (200 mg, 59%). ESI-MS m/z [M+H]+ calc'd for C20H22ClN7OS, 443.95; found 444.3.
