Participants

Reaction Steps

To a solution of rac-6-chloro-3-(3-chloro-benzyl)-3-piperidin-4-yl-1,3-dihydro-indol-2-one (30 mg, 0.08 mmol) (from Example 15a supra) in chloroform (2 mL) was added isocyanatomethane (5.4 mg, 0.096 mmol) (Chem. Service). The mixture was stirred at room temperature for 16 hours. The solvent was evaporated and resulting material was recrystallized from dichloromethane-hexanes to give rac-4-[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 5 mg, 14.5%).
