실험 절차

To a solution of rac-6-chloro-3-(3-chloro-benzyl)-3-piperidin-3-yl-1,3-dihydro-indol-2-one (80 mg, 0.2 mmol) (from Example 25a supra) in dichloromethane (2 mL) was added triethylamine (32.4 mg, 0.3 mmol) (Aldrich), followed by the addition of isocyanatomethane (14.6 mg, 0.24 mmol) (Chem Service). The mixture was stirred at room temperature for 30 minutes. The mixture was then partitioned between ethyl acetate and water. The aqueous layer was extracted with another two portions of ethyl acetate. The combined organic layers were washed with water, brine, dried over Na2SO4 and concentrated. The residue was triturated with dichloromethane-hexanes to give rac-3-[6-chloro-3-(3-chloro-benzyl)-2-oxo-2,3-dihydro-1H-indol-3-yl]-piperidine-1-carboxylic acid methylamide as a white solid. (Yield 35 mg, 50%).
