Reaction Steps
3-Hydroxyadamantane-1-carboxylic acid (500 mg, 2.55 mmol) in dichloromethane (15 mL) was mixed with 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (587 mg, 3.06 mmol), 1-hydroxybenzotriazole (103 mg, 0.765 mmol), N,O-dimethylhydroxylamine hydrochloride (298 mg, 3.06 mmol) and N,N-diisopropylethylamine (1.06 mL, 6.12 mmol) and then stirred at 40° C. for 2 hours. The reaction mixture was stirred with 4-dimethylaminopyridine (779 mg, 6.38 mmol) at 40° C. for 2 hours. After addition of saturated aqueous ammonium chloride, the reaction mixture was extracted with chloroform. The organic layer was washed with 1M hydrochloric acid and saturated aqueous sodium chloride, dried over anhydrous sodium sulfate and concentrated under reduced pressure to give the title compound as a yellow oil (248 mg, yield 41%).
