2-Trifluoromethyl-4-chloro-benzalchloride and 2-methyl-3-nitro-5-chlorobenzotrifluoride, are intermediates in a process of preparing 2-methyl-3-aminobenzo-trifluoride. In this process, 2-trifluoromethyl-4-chlorobenzal-chloride is prepared by chlorinating o-trifluoromethylbenzalhalide, and 2-methyl-3-nitro-5-chlorobenzotrifluoride is prepared at first by hydrogenating the 2-trifluoro-methyl-4-chlorobenzalhalide to form a 2-methyl-5-monochlorobenzotrifluoride and then by nitrating the 2-methyl-5-monochlorobenzotrifluoride. Following this process, 2-methyl-3-aminobenzotrifluoride (MA-BTF) is prepared by hydrogenating the 2-methyl-3-nitro-5-chlorobenzotrifluoride. The thus prepared 2-methyl-3-aminobenzotrifluoride is useful as an intermediate in preparing medicines, agricultural chemicals and other chemical products.
