The use of potassium carbonate in dimethylformamide (DMF) makes it possible to carry out the N-alkylation of isatins with alkyl bromides and iodides and acyl chlorides at room temperature and with alkyl chlorides at elevated temperatures (70-80 deg C) without ring opening.The previously inaccesible N-(2-chloroethyl)isatins were obtained by alkylation of isatin with 1,2-dichloroethane.The condensation of isatins with 1,3-dichloro-2-butene takes place only at the chlorine atom in allyl position of the latter.
