Application of 202925-07-3, 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. 202925-07-3 name is 2-Chloro-1-fluoro-4-methoxybenzene, 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 47; (2-Amino-6-chloro-pyridin-3-yl)-(4-chloro-5-fluoro-2-methoxy-phenyl)-methanone; A. 5-Chloro-4-fluoro-2-iodoanisole; To a solution of 3-chloro-4-fluoroanisole (4.69 g, Lancaster) in chloroform (250 mL) was added silver trifluoroacetate (23.2 g, Aldrich) followed by iodine (15.8 g, Aldrich) in several portions. The reaction mixture was stirred for 2 hours and filtered through Celite. The filtrate was washed with water, brine, dried and concentrated. The crude product was purified by crystallization from ether/petroleum ether to give 5-chloro-4-fluoro-2-iodoanisole (5.0 g). MS (M+H)+, 285.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 2-Chloro-1-fluoro-4-methoxybenzene, and friends who are interested can also refer to it.
