Synthetic Route of 132131-24-9, 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. 132131-24-9, name is 2-Amino-5-iodobenzonitrile belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
Alternative Synthesis of iV-(4-moipholinophenyl)-6-(4-(4-morphoIinophenyIamino)quinazolin-6-yl)quinazolin-4-amine; N’-(2-Cyano-4-iodo~phenyl)-N,N-dimethyl-formamidine:2-Amino-5-iodo-benzonitrile (5g, 20.5mmol) was heated to reflux in DMF-DMA (20ml) for 2h. On cooling and concentrating to dryness in vacuo the residue was filtered through silica (2Og, SiO2) eluting with dichloromethane to afford a brown oil (6.15g, 100%)1H NMR (CDCl3) delta 7.71 ( IH, d), 7.58 ( IH, dd), 7.505 ( IH, s), 6.64 (IH, d), 3.01 (6H, s)LC-MS rt 3.46 m/z 299 MH+; Example 2; N*4*-(4-Morpholin-4-yI-phenyl)-N*4*-phenyl-[6,6′]biquinazolinyl-4,4′- diamine; N’-(2-Cyano-4-iodo-phenyl)-N,N-dimethyl-formamidine; 2-Amino-5-iodo-benzonitrile (5g) in DMF-DMA ( 10ml) was heated to 110 for 2h. The cooled reaction mixture was diluted with water (100ml) and extracted into ethyl acetate (3xl00ml). The combined organic phases were dried (MgSO4) and concentrated to give a viscous brown oil (~ quantitative) which was used without further purification.1H NMR (CDCl3) delta 7.77 (IH, m), 7.65 (IH, dm, J8.85Hz), 7.57 (IH, s), 6.70 ( IH, d,J8.85Hz), 3.012 (6H, s)LC-MS rt 3.46 m/z 299.78
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, 2-Amino-5-iodobenzonitrile, other downstream synthetic routes, hurry up and to see.
