Reference of 193354-13-1, 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. 193354-13-1 name is 5-Iodoindolin-2-one, 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.
5-Methoxycarbonyl-2-oxindole 5-Iodo-2-oxindole (17 g) was refluxed with 2 g of palladium diacetate, 18.2 g of triethylamine, 150 ML of methanol, 15 ML of dimethylsulfoxide and 2.6 g of DPPP in an atmosphere saturated with carbon monoxide.. After 24 hours, the reaction was filtered to remove the catalyst and the filtrate concentrated.. The concentrate was chromatographed on silica gel (30% ethyl acetate in hexane).. The fractions containing product were concentrated and allowed to stand.. The precipitated product was collected by vacuum filtration to give 0.8 g (7%) of the title compound as an off-white solid.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 5-Iodoindolin-2-one, and friends who are interested can also refer to it.
