Condensation of 1-substituted or 1,3-disubstituted 5-bromo-6-methyluracils (4) and aromatic amines gave the corresponding 6-arylaminomethyluracil derivatives (5). Treatment of 5-bromo-6-bromomethyl-1,3-dimethyluracil (10) with primary aromatic amines gave the corresponding 6-arylidenemethyluracil derivatives (11). Reaction of (10) with N-methylaniline gave 5-bromo-1,3-dimethyl-6-(N-methylanilino)methyluracil
1-取代或1,3-二取代的5-溴-6-甲基尿嘧啶(4)和芳族胺的缩合得到相应的6-芳基氨基甲基尿嘧啶衍生物(5)。用伯芳族胺处理5-溴-6-溴甲基-1,3-二甲基尿嘧啶(10),得到相应的6-亚芳基甲基尿嘧啶衍生物(11)。(10)与N-甲基苯胺的反应得到5-溴-1,3-二甲基-6-(N-甲基苯胺基)甲基尿嘧啶(13a),将其进一步用伯芳族胺处理得到(11)。
