Synthetic Route of 35944-64-0, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 35944-64-0, name is 3-Iodo-4-methylaniline belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
2-Chloroisonicotinic acid (3.3g, 21mmol), HATU (8.75g, 23mmol), diisopropylethyl amine (10. 9ml, 63mmol) and 3-iodo-4-methylaniline (5. 00g, 21mmol) in dimethylformamide (50ml) were heated under nitrogen for 16 hours. The reaction was cooled, solvent removed in vacuo and the residue taken up in dichloromethane (150ml). The organic solution was washed with water (3xlOOml) and brine (100ml), dried over magnesium sulfate, filtered and solvent removed in vacuo. The residue was purified by column chromatography (40: 60 ethyl acetate: cyclohexane) to give 2-chloro-N- (3-iodo-4- methylphenyl) -isonicotinamide as a white solid (7. 00g, 18. 8mmol). LCMS: retention time 3.59 min Mu373. NMR: 8H [2H6]-DMSO 10.52 (1H, s), 8.62 (1H, d), 8.29 (1H, d), 7.99 (1H, b), 7.87 (1H, dd), 7.70 (1H, dd), 7.34 (1H, d), 2.36 (3H, s).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 3-Iodo-4-methylaniline, other downstream synthetic routes, hurry up and to see.
