Paragraph 0080-0085, (2019/08/01)
The invention belongs to the technical field of chemical synthesis of medicines, and belongs to the technical field of pharmaceutical chemistry. The invention particularly relates to a green preparation method. The o-methyl aniline and N - chlorosuccinimide are chlorinated to obtain 2 - methyl -5 - chloro- aniline; the 6 - chlorine - 222H-indole hydrochloride is obtained by reacting with the nitrous acid compound; N-methyl -6 -chloro - 222H-indole; under the participation of dimethyl sulfoxide, 3 - 2-dimethyl 3 - chlorine -6 - 222H-indazole; and the like. A reaction with 2 - chloro -4 - amino - pyrimidine and iodomethane gave N - (2 -chloropyrimidine -4 -yl) - N N-methyl -2, 3 -dimethyl - 222H-indazole -6 - amine; and finally, a pimatinib hydrochloride salt was obtained by reaction with 3 - sulfanilide -4 - methyl - aniline. The method is low in raw material price, simple to operate, low in operation risk, capable of avoiding waste acid generation, high in reaction yield, and high in purity. (by machine translation)
Alpha-substituted pyrimidine-thioalkyl and alkylether compounds as inhibitors of viral reverse transcriptase
-
, (2008/06/13)
The subject invention relates to pyrimidine-thioalkyl and alkylether compounds of Formula (I) and pyrimidine-thioalkyl and alkylethers of Formula (IA), namely the compounds of Formula (I) where R 4 is selected from the group consisitng of --H or --NR 15 R 16 where R 15 is --H and R 16 is --H, C 1 -C 6 alkyl, NH 2 or R 15 and R 16 taken together with the --N form 1-pyrrolidino, 1-morpholino or 1-piperidino; and R 6 is selected from the group consisting of --H, or halo (preferably --Cl); with the overall proviso that R 4 and R 6 are not both --H. The compounds of Formula (IA) are useful in the treatment of individuals who are HIV positive being inhibitors of viral reverse transcriptase. STR1
