A series of new 2-(phenyl)-1,3- and 2-(phenyl)-1,3,3-tetramethylguanidines ( a-k ) were synthesized by reaction of different substituted aniline and urea derivatives in the presence of phosphorus oxychloride. The yields of products following extraction from toluene without further purification were of the order of 50-70%. We have found that adjusting of the pH at 8-9 in the work up process increases
通过不同取代苯胺和尿素衍生物在三氯化磷存在下反应合成了一系列新的2-(苯基)-1,3-和2-(苯基)-1,3,3-四甲基胍(ak)。从甲苯中提取而无需进一步纯化后的产物产率约为50-70%。我们已经发现,在后处理过程中将 pH 值调节为 8-9 会增加产品的产率。IR、 1 HNMR 和质谱也用于鉴定这些化合物。
