Application of 22236-10-8, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 22236-10-8 name is 4-(Difluoromethoxy)aniline, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
Example 12; 2-ButyI-5-(4-chIorophenyl)-4-{[4-(difluoromethoxy)phenyl]amino}isothiazol-3(2H)-one 1,1-dioxide; 2-Butyl-4-chloro-5-(4-chlorophenyl)isothiazol-3(2H)-one 1,1-dioxide (0.2Og, 0.60mmol) and 4-(difiuoromethoxy)-aniline (0.19Og, 1.20mmol) were mixed in MeCN (2.5mL). The mixture was heated in a microwave reactor at 130 C for 15 mins, then additional 60 mins and then at 140 0C for 15 mins, then additional 30 mins. The mixture was evaporated and the residue was purified by column chromatography (ISOLUTE SI 20 g/70 mL), eluting with heptane, then DCM:heptane (25:75, then 50:50), to give the title compound (0.122g, 45%);
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 4-(Difluoromethoxy)aniline, and friends who are interested can also refer to it.
