Thionyl chloride (26 μL, 0.35 mmol) was added to (1-(5-phenylthieno[2,3-d]pyrimidin-4-yl)piperidine-4-carboxylic acid (100 mg, 0.294 mmol) in dry DCM at 0° C. The reaction was stirred for 30 min then 2-(1-methylpyrrolidin-2-yl)ethanamine (173 μL, 0.294 mmol) and triethylamine (82 μL, 0.588 mmol) were added and the reaction stirred for a further 10 min at 0° C. and then stirred at room temperature for 1 hr. The reaction was reduced to dryness in vacuo and the residue purified by prep HPLC (Basic, method F) to give the desired compound as an off-white solid. Yield=70 mg. LCMS [M+H]+=450; RT=3.01 min
