摘要:
The present invention provides a method for the reductive acetamidation of an aryl nitro compound by reacting a substituted acid with an aryl nitro compound and adding a catalytic amount of a base with the substituted acid and the aryl nitro compound to form an acetamidation aryl nitro compound. The acetamidation aryl nitro compound is then purified.
摘要:

摘要:
A process of reacting a nitroaniline compound of formula (2): with an acid anhydride or acid halide is carried out in the presence of an alkali metal compound or an alkaline earth metal compound to produce an acylnitroaniline derivative. The process further includes the step of reacting the resulting product with a compound of formula (5); R2—Y to produce an N-acylnitroaniline derivative of formula (1): The N-acylnitroaniline derivative of formula (1) is a useful intermediate for the production of pharmaceuticals.
摘要:
The present invention provides an aniline derivative represented by the formula (I) wherein R1 and R2 are each H, (C1-12)alkyl, (C3-8)cycloalkyl, hydroxy(C1-12)alkyl, hydroxycarbonyl (C1-12)alkyl, (C1-6)-alkoxycarbonyl(C1-6)alkyl, —COR8, wherein R8 is H, halo-(C1-12)alkyl, (C3-8)cycloalkyl or (substituted) phenyl, COOR9, wherein R9 is a halo(C1-6)alkyl group, (substituted) phenyl or (substituted) benzyl; R3, R4, R5, R6and R7 are each H, halogen, OH, nitro, halo(C1-12)alkylthio, (substituted)amino-(C1-2)alkyl, (substituted) phenyl, (substituted) benzyl, amino, —N(R10)R11 wherein R10 and R11 are each H, alkyl, cycloalkyl, (substituted) phenyl, (substituted) benzyl, —COR8 or COOR9, or (C2-27)perfluoroalkyl, etc., and a process for producing the aniline derivative. According to the process of the present invention, perfluoroalkylaniline derivatives can be obtained by using various anilines as the substrate with a high position selectivity and high yield.
