4-氯-2-(3-吡啶)-6-甲基嘧啶 | 4-chloro-6-methyl-2-(pyridin-3'-yl)pyrimidine | 83551-42-2 | C10H8ClN3 | 205.647 |
The condensation of 3-aminocrotonamide with ethyl pyridine-2-carboxylate or a related ester gave 6-methylpyrimidin-4(3H)-ones, each bearing at its 2-position a pyridin-2'-yl, pyridin-3'-yl, pyridin- 4'-yl, furan-2'-yl, furan-3'-yl, thien-2'-yl or pyrazin-2'-yl substituent. Of these, the pyridinyl derivatives (1a), (2a) and (3a) were converted into their 4-chloro analogues and thence by nucleophilic displacement into the corresponding β-dimethylaminoethylthio, β-dimethylaminoethylamino, β-dimethylaminoethoxy and γ-dimethylaminopropylamino derivatives. The activities of these compounds as amplifiers of phleomycin against Escherichia coli are reported.
