| Abstract: | In this paper,2,5 dimethoxy 4 chloro N acetoacetyl aniline was prepared with a yield of 92% on basis of the material 2,5 dimethoxy 4 chloro aniline by acetoacetanization with 2,5 dimethoxy 4 chloro aniline and diketene.Moreover,the C.I.PY83 pigment was manufctured with a yield of 95% by coupling the said intermediate,2,5 dimethoxy 4 chloro acetoacetanilide with diazotised DCB. |
