    摘要: Processes for preparing substituted oxindole-2-ones, and specifically the following, are described, wherein R1-R4, R6, and n are defined herein. The processes include reacting a first alkali metal hydroxide, a tetraalkyl ammonium salt, a benzonitrile, and R6X or XCH2(CH2)nX′, wherein R6 is C1 to C6 alkyl, substituted C1 to C6 alkyl, C3 to C8 cycloalkyl, substituted C3 to C8 cycloalkyl, aryl, substituted aryl, heteroaryl, substituted heteroaryl, heterocyclic, or substituted heterocyclic, X and X′ are, independently, leaving groups, and n is 1 to 5; (ii) reacting the product of step (i) with a second alkali metal hydroxide at a temperature of at least about 60° C.; (iii) reacting the product of step (ii) with an alkali alkoxide at a temperature of at least about 140° C. to form an oxindol-2-one; (iv) brominating the oxindol-2-one; and (v) coupling the brominated oxindol-2-one with a coupling reagent.
