Adding a certain compound to certain chemical reactions, such as: 132131-24-9, name is 2-Amino-5-iodobenzonitrile, belongs to iodides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 132131-24-9, Recommanded Product: 132131-24-9
(ii) Preparation of N’-(2-cyano-4-iodo-phenyl)-N,N-dimethyIformamidine (8): Into a 500 ml 3 necked round bottomed flask, N, N-dimethylforamide (100 ml), 2- amino-5-iodobenzonitrile (50g) obtained by the process given in the above step (i) and Nu,Nu-dimethyl formamide dimethyl acetate (51.3 g) were charged. The reaction mass was maintained at 70-75 C for about 2 Hrs. The completion of the reaction was monitored by TLC. The reaction mass was cooled to 25-35 C and quenched into ice water and maintained for about 2 Hrs. at 0-5 C. The product was filtered and dried under vacuum at 25-35 C to get 58 g of N’-(2-cyano-4-iodo-phenyl)-N,N- dimethylforrnamidine as a pale yellow coloured amorphous powder. Melting range: 53-55 CHPLC purity: 99.8%
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 2-Amino-5-iodobenzonitrile, and friends who are interested can also refer to it.
