Reaction Steps

At room temperature, 4-{[6-Chloro-3-(3-chloro-benzyl)-2-oxo-2,3-dihydro-1H-indol-3-yl]-cyclobutylcarbamoylmethyl-amino}-piperidine-1-carboxylic acid tert-butyl ester (700 mg, 1.17 mmol) was dissolved a mixture solution of CF3COOH and CH2Cl2. After stirred 0.5 h, the solution was concentrated and the organic layer was washed with NaOH aqueous solution. The organic layer was dried, concentrated to obtain crude product. The crude product was purified by chromatography to obtain 200 mg rac-2-{[6-Chloro-3-(3-chloro-benzyl)-2-oxo-2,3-dihydro-1H-indol-3-yl]-piperidin-4-yl-amino}-N-cyclobutyl-acetamide.
