Procedure

HATU (0.105 g, 0.28 mmol) was added into a mixture of 5-methyl-4-(2-(tetrahydro-2H-pyran-4-yloxy)pyridin-3-ylamino)thieno[2,3-d]pyrimidine-6-carboxylic acid (0.097 g, 0.25 mmol) and Hünig's base (44 μL, 0.25 mmol) in DMF (2.0 mL) at 0° C. The reaction mixture was stirred at 0° C. for 0.5 hours. N,N-Dimethylethylenediamine (137 μL, 1.25 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 off-white solid (0.026 g, 22%).
