실험 절차

4-Cyano-3-hydroxybenzoic acid methyl ester, Example 34 Step 3 (300 mg, 1.7 mmol) was dissolved in DMF (85 ml) and treated with phenylbutylchloride (287 mg, 1.7 mmol). Cs2CO3 (610 mg, 1.87 mmol) was then added and the reaction mixture stirred at room temp. for 18 hours. The mixture was filtered and washed with DMF (3×10 mL). The solvent was removed in vacuo and the residue was purified by flash chromatography (10% EtOAc/Hexane) to yield desired product.
