Procedure
Under an argon atmosphere, anhydrous methylene chloride (0.5 mL) and triethylamine (10 μL, 0.069 mmol) were added to N-[2-fluoro-4-(methylsulfonyl)phenyl]-7-(piperidin-4-yl)furo[3,2-d]pyrimidine-4-amine hydrochloride (10 mg, 0.023 mmol), picolinic acid (3.3 mg, 0.028 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (9 mg, 0.046 mmol) and N,N-dimethylaminopyridine (0.3 mg, 0.002 mmol), followed by stirring at room temperature for 2 hours. Water was added to the reaction liquid, the reaction liquid was extracted with chloroform, the organic layer was dried over anhydrous sodium sulfate and concentrated under a reduced pressure, and the obtained residue was purified by silica gel preparative thin layer chromatography (chloroform:methanol=20:1) to give the titled compound (3.3 mg, 35%) as a yellow oily substance.
