2-(呋喃-2-基)-6-甲基嘧啶-4-胺 | 2-furan-2-yl-6-methyl-pyrimidin-4-ylamine | 27130-89-8 | C9H9N3O | 175.19 |
4-氯-2-[2]呋喃基-6-甲基-嘧啶 | 4-chloro-2-[2]furyl-6-methyl-pyrimidine | 28021-53-6 | C9H7ClN2O | 194.62 |
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.
