실험 절차

To solution of 2-(4-adamantan-1-yl-phenoxymethyl)-benzoxazole-5-carboxylic acid (60.4 mg, 0.15 mmol), dimethyl amine (0.030 ml, in 2M THF) in DMF 5.0 mL was added HBTU (113.8 mg, 0.30 mmol) and DIPEA (0.052 ml, 0.30 mmol). After sting at room temperature, the mixture was partitioned between ethyl acetate and brine. The organic phase was dried (MgSO4 anh), and concentrated. The residue was purified by silica gel column chromatography (n-Hexane:EtOAc:MeOH=15:3:1) to give 2-(4-adamantan-1-yl-phenoxymethyl)-benzoxazole-5-carboxylic acid dimethylamide as a white solid (37.9 mg, 59% yield).
