반응 단계
To the product of Step 1 (216 mg) dissolved in acetonitrile (4 mL) was added Et3N (0.26 mL), followed by 4-fluorophenylacetic acid (102 mg). After 1.5 h at room temperature 0.23 mL of DBU was added. The reaction mixture was stirred for another 45 min and then treated with 5 mL of 1N HCl. The product was extracted with EtOAc, dried over Na2 SO4 and concentrated. The residue was purified by flash chromatography (40% EtOAc in hexane) to yield 150 mg of the title compound as a solid.
