6-甲基-2-吡啶-3-基嘧啶-4(3H)-酮 | 6-methyl-2-(pyridin-3-yl)pyrimidin-4(3H)-one | 16879-57-5 | C10H9N3O | 187.201 |
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.
