Triethylamine → HCID 11999234, compound

Participants

Reaction Steps

To a solution of rac-6-chloro-3-(3-chloro-benzyl)-3-piperidin-3-yl-1,3-dihydro-indol-2-one (112 mg, 0.3 mmol) (from Example 25a supra) in dichloromethane (3 mL) was added triethylamine (45.5 mg, 0.45 mmol) (Aldrich), followed by the addition of 1-isocyanato-4-methylsulfanyl-benzene (59.4 mg, 0.36 mmol) (Aldrich). The mixture was stirred at room temperature for 30 minutes. The mixture was partitioned between dichlormethane and water. The aqueous layer was extracted with dichlormethane. The combined organic layer was washed with water, brine, dried over MgSO4 and concentrated. The residue was purified by chromatography to give rac-3-[6-chloro-3-(3-chloro-benzyl)-2-oxo-2,3-dihydro-1H-indol-3-yl]-piperidine-1-carboxylic acid (4-methylsulfanyl-phenyl)-amide as a white solid (Yield 0.13 g, 80%).
