Hydantoin derivatives are industrially advantageously produced at a high yield by reacting hydantoin with carbonyl compounds in the presence of (i) amino acids or the salts thereof and (ii) inorganic alkali compounds for a relatively short reaction time in an aqueous medium.
在水介质中,通过在(i)氨基酸或其盐和(ii)无机碱化合物的存在下,将咪唑二酮与羰基化合物反应,可以高产地工业优势地生产咪唑二酮衍生物,反应时间相对较短。
