Syntheses of 2-chloro-4-acetylaminobenzonitrile isomers and structurally related compounds with biological activities was written by Grivsky, Eugene M.;Hitchings, George H.. And the article was included in Industrie Chimique Belge in 1974.Product Details of 53312-77-9 This article mentions the following:
Benzonitriles I, II, and III (Xn = 2-,3-Cl, 2-F, 2,6-, 2,4 -Cl2; NH2, NHCOR, NO2 in 2, 4, or 5 position; R = e.g., Me, H, CF3, CHCl2, CH2Cl, Et, Me2CH, Pr, CH:CHCO2H, CH2CH2CO2H) were prepared (5 I, 15 II and 88 III). E.g., reaction of 2,4-F-(O2N)C6H3CO2H with MeSO2NH2-PCl5 gave 96% I (Xn = 2-F, 4-NO2), which was reduced to give II (Xn = 2-F, 4-NH2), which was acetylated to give 95% III (Xn = 2-F, R = Me). III (Xn = 2-Cl, NHCOMe in 4 position) had LD50 (oral-mice)of 1800 mg/kg; and at 20 mg/kg (oral-mice) was an antide-pressant and at 25 and 50 mg kg (orally-rat), resp., was an anal-gesic and antipyretic. In the experiment, the researchers used many compounds, for example, 2-Amino-3-chlorobenzonitrile (cas: 53312-77-9Product Details of 53312-77-9).
2-Amino-3-chlorobenzonitrile (cas: 53312-77-9) belongs to nitriles. Nitrile compounds can be prepared by the incorporation of a cyanide source through C–C bond formation or by dehydration of primary carboxamides. Asymmetric bioreduction of nitriles is an attractive route to produce optically active nitriles as current metal-catalyzed hydrogenations tend to have low reactivity.Product Details of 53312-77-9
