Formula: C9H9NO2, Modeling chemical reactions helps engineers virtually understand the chemistry, optimal size and design of the system, and how it interacts with other physics that may come into play.
General procedure: To a solution of the corresponding substituted oxindole (5, 40 mmol) and triethylamine (88 mmol) in THF (140 mL) was added phenyl chloroformate (13.76 g, 11.0 mL, 88 mmol) dropwise. The temperature was kept below 30 C during the addition. After stirring for 30 min at room temperature, the solvent was evaporated. Water (40 mL) was added to the residue and the mixture was stirred for 2 h at 0-5 C. The crystalline product was filtered and recrystallized from ethyl acetate to give compounds 6.
