 After this first step, an addition reaction with "perfluoro-vinyl-perfluoro-methyl ether" is conducted to synthesize "3-chloro-4-[1,1,2-trifluoro2-(trifluoromethoxy)-ethoxy]aniline".The next step in the process is the production of "2,6-difluorobenzoyl isocyanate" in an acylation reaction using "2,6-difluorobenzamide" and "oxalyl dichloride".The final part of the synthesis of novaluron is an addition reaction with "3-chloro-4-[1,1,2-trifluoro-2-(trifluoromethoxy)-ethoxy]aniline".
