2-Chloro-4-sulfamoylbenzoic acid (cas: 53250-84-3) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Recommanded Product: 53250-84-3
Acridine derivatives as antimalarials. II was written by Basu, U. P.;Das-Gupta, S. J.. And the article was included in Journal of the Indian Chemical Society in 1939.Recommanded Product: 53250-84-3 The following contents are mentioned in the article:
2-Chloro-4-sulfonamidotoluene (I), m. 121-3°, was prepared by reacting o-chlorotoluene and chlorosulfonic acid (1:5) at a low temperature and finishing the reaction by heating the mixture at 60° for 2 hrs., cooling over ice and treating with NH4OH. Oxidation of I with 10% KMnO4 gave 2-chloro-4-sulfonamidobenzoic acid (II), m. 198-9°. A mixture of II (2.3 g.), 1.2 g. p-anisidine, 1.4 g. anhydrous K2CO3, 0.1 g. Cu powder and 25 cc. AmOH was refluxed for 5 hrs. to give 5-sulfonamido-4′-methoxydiphenylamine-2-carboxylic acid (III), m. 242°. III, heated at 100° for 2 hrs. with excess POCl3 gave 2-sulfonamido-5-chloro-7-methoxyacridine (IV), m. 240°. IV (1 g.) was dissolved in PhOH and heated with 0.7 g. δ-diethylamino-α-methylbutylamine for 1 hr. The reaction mixture was poured into NaOH solution and extracted with Et2O to give 2-sulfonamido-7-methoxy-5-(ω-diethylaminoisoamyl)aminoacridine, m. 115-20°. Similarly IV with δ-diethylaminobutylamine in PhOH gave 2-sulfonamido-7-methoxy-5-(δ-diethylaminobutyl)aminoacridine, m. 110-5°. Using similar technics the following were prepared: 2-chloro-5-sulfonamidobenzoic acid, m. 217-19°; 2-chloro-5-sulfondiethylamidobenzoic acid, m. 147°; 2-chloro-5-sulfonphenylamidobenzoic acid, m. 194-5°; 4-sulfonamido-4′-methoxydiphenylamine-2-carboxylic acid, m. 239-40°; 4-sulfondiethylamido-4′-methoxydiphenylamine-2-carboxylic acid, m. 170-1°; 4-sulfonphenylamido-4′-methoxydiphenylamine-2-carboxylic acid, m. 233°; 3-sulfonamido-3-chloro-7-methoxyacridine, m. above 230° (decomposition); 3-sulfondiethylamido-5-chloro-7-methoxyacridine, m. 184-6°; 3-sulfonphenylamido-5-chloro-7-methoxyacridine, m. 207-8°; 3-sulfonamido-7-methoxy-5-(ω-diethylaminoisoamyl)aminoacridine, m. 135° (indefinite); 3-sulfonamido-7-methoxy-5-(δ-diethylaminobutyl)aminoacridine, m. 138° (indefinite); 3-sulfondiethylamido-7-methoxy-5-(ω-diethylaminoisoamyl)aminoacridine, m. 105-10°; 3-sulfophenylamido-7-methoxy-5-(ω-diethylaminobutyl)aminoacridine, m. 100-5°; 5-chloro-4′-sulfonamidodiphenylamine-4-carboxylic acid, m. 207°; 5-chloro-4′-acetylaminodiphenylamine-2-carboxylic acid, m. 287-8°; 2,5-dichloro-7-acetylaminoacridine, m. 242-3°; 2-chloro-7-aminoacridone, m. 250° (decomposition). This study involved multiple reactions and reactants, such as 2-Chloro-4-sulfamoylbenzoic acid (cas: 53250-84-3Recommanded Product: 53250-84-3).
