| titleOfInvention | Method for preparing 2,4,6-triiodobenzene derivative substituted with 1,3,5-position |
| abstract | The present invention relates to a method for preparing a 2,4,6-triiodobenzene derivative substituted with a 1,3,5-position, wherein 1,3,5- under a mixed solvent of methanol and dichloromethane (CH 2 Cl 2 ) 2,4,6-triiodine substituted with 1,3,5-position of the following general formula (1), which is an important intermediate of the X-ray contrast agent by reacting a substituted benzene derivative with iodine chloride (ICl) and a base Benzene derivatives can be prepared in high purity and high yield:n n n (One)n n n Wheren n n R 1 is a hydroxy, amino or nitro group;n n n R 2 and R 3 are each independently a C 1-5 alkyl group, CO 2 R 4 or COR 5 ;n n n R 4 is hydrogen or a C 1-7 alkyl group;n n n R 5 is a C 1-3 alkylamino group, -N (R 6 ) CH 2 CH (OR 7 ) CH 2 OR 7 , -N (R 6 ) CH (CH 2 OR 7 ) CH (OR 7 ) CH 2 OR 7 Or —N (R 6 ) CH (CH 2 OR 7 ) CH 2 OR 7 , wherein R 6 and R 7 are each independently hydrogen, a C 1-3 alkyl group, or a C 1-3 acyl group. |
