Reaction Steps

HATU (0.052 g, 0.138 mmol) was added into a mixture of methyl 4-(4-fluoro-2-(tetrahydro-2H-pyran-4-yloxy)phenylamino)-5-methylthieno[2,3-d]pyrimidine-6-carboxylate (0.050 g, 0.125 mmol) and Hünig's base (22 μL, 0.125 mmol) in DMF (2.0 mL) at 0° C. The reaction mixture was stirred at 0° C. for 0.5 hours. Dimethylamine (2M in THF, 1.0 mL, 2.0 mmol was added and the coolant removed. The reaction mixture was stirred at ambient temperature overnight. The solvent was concentrated in vacuo and the product purified by reverse phase preparative HPLC to yield white solid (0.017 g, 30%).
