The reaction was carried out in 30% alcohol and 5% acetic acid, and the ratio of the pyrimidine-thione/pyruvic acid reagents was 1:3. In aqueous alcohol, the reaction took 12 h, while in acetic acid, it was complete in 2 h. The TLC, IR, PMR and mass spectroscopy data showed that the product of this reaction (III) was isolated in individual state and had the same structure, irrespective of the solvent
反应在30%乙醇和5%乙酸中进行,嘧啶-硫酮/丙酮酸试剂的比例为1:3。在乙醇水溶液中,反应需要 12 小时,而在乙酸中,反应在 2 小时内完成。TLC、IR、PMR 和质谱数据表明,无论使用何种溶剂,该反应 (III) 的产物均以单独的状态分离并具有相同的结构。我们没有观察到具有异构结构(III和IIIa)的化合物混合物的形成
