3-(2-Chlorothieno[3,2-d]pyrimidin-7-yl)benzoic acid (600 mg, 2.06 mmol) was dissolved in N,N-dimethylformamide (20 mL) and then cyclopropylamine (234 mg, 4.12 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (589 mg, 3.09 mmol), hydroxybenzotriazole (417 mg, 3.09 mmol) and trimethylamine (574 mL, 4.12 mmol) were added. The reaction mixture was stirred at room temperature for a day, diluted with ethyl acetate, and washed with ammonium chloride aqueous solution. The organic layer was dried with magnesium sulfate, filtered with celite, and then concentrated. Purification by chromatography (20% ethyl acetate/hexane) yielded the target compound (580 mg, 85% yield).
