Preparation and Identification of Some New Derivatives of 4-Bromoaniline

Abstract

This paper is ensured synthesis of some heterocycle derivatives of 4-bromoaniline compound thatlikely they are to be effective vital task was diagnosed spectrally by spectrum of IR and the spectrumof NMR (1H & 13C), as well as using C.H.N. analysis and study of some physical properties.Derivatives (1-5) was prepared as benzothiazole derivatives, (1) derivative was prepared byreacting 4-bromoaniline with ammonium thiocyanate existence Br2 as a catalyst and glacial acetic acidas medium of reaction and attended (2) & (3) derivatives by smelting of maleic and phthalic anhydridewith (1) derivative, respectively, also attended the (4) derivative by reactance (1) derivative withpotassium thiocyanate ,using the technique of microwave, (5) derivative prepared from (1) by usingmicrowave technique and follow the Suzuki reaction and presence of 4-cyanophenyl boronic acid,while (7) & (8) derivatives prepared as thiazolidine derivatives from (6) derivative that was preparedby reactance 4-bromoaniline with chloroacetylchloride, by it reacting with potassium and ammoniumthiocyanate, respectively.
