実験手順

To solution of 2-(4-adamantan-1-yl-phenoxymethyl)-benzoxazole-5-carboxylic acid (72.1 mg, 0.18 mmol), ammonium chloride (19.1 mg, 0.36 mmol) in DMF 4.0 mL was added HBTU (136.53 mg, 0.36 mmol) and DIPEA (0.063 ml, 0.36 mmol). After stirring 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 (CH2Cl2:MeOH=15:1) to give 2-(4-adamantan-1-yl-phenoxymethyl)-benzoxazole-5-carboxylic acid amide as a yellow solid (2.7 mg, 4% yield).
