5-Alkyl-6-(substituted benzyl)-2-thiouracils 3a,c were reacted with (2-chloroethyl) diethylamine hydrochloride to afford the corresponding 2-(2-diethylamino)ethylthiopyrimidin-4(3H)-ones 4a,b. Reaction of 3a–c with N-(2-chloroethyl)pyrrolidine hydrochloride and/or N-(2-chloroethyl)piperidine hydrochloride gave the corresponding 2-[2-(pyrrolidin-1-yl)ethyl]-thiopyrimidin-4(3H)-ones 5a–c and 2-[2-(piperi
5-烷基-6-(取代苄基)-2-硫尿嘧啶3a,c与(2-氯乙基)二乙胺盐酸盐反应,得到相应的2-(2-二乙氨基)乙基硫嘧啶-4(3H)-酮4a,b。3a-c 与 N-(2-氯乙基)吡咯烷盐酸盐和/或 N-(2-氯乙基)哌啶盐酸盐反应得到相应的 2-[2-(吡咯烷-1-基)乙基]-硫嘧啶-4(3H )-ones 5a–c 和 2-[2-(piperidin-1-yl)ethyl]thiopyrimidin-4(3H)-ones 6a,b,分别。在相同反应条件下用 N-(2-氯乙基)吗啉盐酸盐处理 3a-d 形成相应的 2-[2-(吗啉-4-基)乙基]硫嘧啶 6c-f。另一方面,3a、b与N-(2-溴乙基)邻苯二甲酰亚胺和/或N-(3-溴丙基)邻苯二甲酰亚胺反应以提供相应的2-[2-(N-邻苯二甲酰亚胺)乙基]-嘧啶7a,b 和 2-[3-(N-邻苯二甲酰亚胺)-丙基]嘧啶 7c,d 分别。针对革兰氏阳性菌(金黄色葡萄球菌
