Versuchsvorschrift

HATU (0.157 g, 0.41 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 (0.145 g, 0.38 mmol) and Hünig's base (65 μL, 0.38 mmol) in DMF (2.0 mL) at 0° C. The reaction mixture was stirred at 0° C. for 0.5 hours. Tert-butyl-N-(2-aminoethyl) carbamate (296 μL, 1.88 mmol) was added and the coolant removed. The reaction mixture was stirred at ambient temperature overnight. The solvent was concentrated in vacuo and the crude product dissolved in DCM. The organic layer was washed with water, concentrated in vacuo (10 mL) and trifluoroacetic acid added (3.0 mL). The mixture was stirred at ambient temperature overnight, concentrated in vacuo and purified by ion-exchange chromatography (SCX-2 eluting with hydrochloric acid/MeOH→ammonia/MeOH). Further purification by flash-column chromatography (100% DCM→10% ammonia/MeOH/DCM) yielded the title compound as pale yellow solid (0.063 g, 39%).
