HATU (0.073 g, 0.193 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 (0.07 g, 0.175 mmol) and Hünig's base (30 μL, 0.175 mmol) in DMF (2.0 mL) at 0° C. The reaction mixture was stirred at 0° C. for 0.5 hours. N1,N1-dimethylbutane-1,4-diamine (0.177 g, 0.875 mmol) was added, the coolant removed and the reaction stirred at ambient temperature overnight. The crude reaction mixture was applied to an SCX cartridge and eluted with MeOH (30 mL) followed by ammonia in MeOH. The product was purified by flash column chromatography (10% MeOH/DCM→15% MeOH/DCM/0.5% NH4OH) to give the title compound as a waxy colourless solid (0.012 g, 37%).
