7-dihydro-imidazo[1,2−a]-s-triazines (IV, VII, X and XV) have been synthesized according to the following scheme: (a) monosubstitution of cyanuric chloride (I) with ethanolamine, (b) replacement of the remaining chlorine atomes by suitable groupe, and (c) cyclisation of the 2′-hydroxy-ethylamino side chain on one of the adjacent cyclic nitrogen atoms of the s-triazine nucleus. This last step includes reaction of
四2,4-二取代的-6,7-二氢-咪唑并[ 1,2 - A] -s-三嗪(IV,VII,X和XV)已经根据下述方案合成:氰尿酰氯的(a)单取代( I)用乙醇胺,(b)用合适的基团替换剩余的氯原子,和(c)在s-三嗪核的相邻环状氮原子之一上的2'-羟基-乙基氨基侧链环化。最后的步骤包括使2-[((2-羟基-乙基)-氨基] -s-三嗪与硫代氯化物或对甲苯磺酰氯反应,并且除了(VIIIIX)外,加热所得的2-[((2-溶剂中的氯-乙基)-氨基]衍生物或对甲苯磺酸酯。
