실험 절차

To a solution of 2-(4-methoxy-benzyl)-8-((3R,4S)-4-phenyl-pyrrolidin-3-ylmethyl)-2,8-diaza-spiro[4.5]decan-1-one (60 μmol) in anhydrous DCM (1 mL) was added isopropylchloroformate (180 μL, 1M in toluene, 180 μmol) and triethylamine (29 μL, 55 μmol). The reaction mixture was stirred overnight at room temperature. Saturated sodium bicarbonate aqueous solution was added to the reaction mixture and the aqueous layer washed with dichloromethane (3×2 mL). The organic layer was then concentrated in vacuo and purified by semi-preparative HPLC (Method D) and lyophilized to give the Compound 183 as a colorless solid (15.3 mg, 50%).
