Procedure
4-Adamantan-1-yl-phenoxy acetic acid (143.2 mg, 0.5 mmol) was dissolved in 5 ml of THF and oxalyl chloride (178.5 mg, 0.11 ml, 1.5 mmol), to which DMF was added. After reacting the mixture at room temperature for 1 hour, 3-amino-4-hydroxy-benzoic acid methyl ester (125.4 mg, 0.75 mmol) and pyridine (0.05 ml) were added thereto. The reaction mixture was reacted at room temperature. Upon completion of the reaction, the reaction mixture was extracted with ethylacetate and NaCl solution, thereafter the organic layer was dried over anhydrous MgSO4, and concentrated. The residue was purified by silicagel column chromatography (N-Hexane: EtOAc:MeOH=6:3:1) to give the target compound as a white solid (183.2 mg, yield: 84.1%).
