Abstract The Pinner synthesis was applied to the preparation of 4-(cyclic amidino)phenols in high yields from readily available 4-hydroxybenzimidic acid methyl ester hydrochloride and diaminoalkanes. An alternative attempt was made to convert 4-(hydroxy)thiobenzamide to 4-(1,4,5,6-tetrahydro-5-hydroxy-2-pyrimidiyl)phenol. A procedure for the preparation of 3,6-bis(4-hydroxyphenyl)- 1,2,4,5-tetrazine
摘要 Pinner 合成法用于从易得的 4-羟基苯甲酸甲酯盐酸盐和二氨基烷烃中以高收率制备 4-(环脒基)苯酚。另一种尝试是将 4-(羟基) 硫代苯甲酰胺转化为 4-(1,4,5,6-四氢-5-羟基-2-嘧啶基)苯酚。此处报道了制备 3,6-双(4-羟基苯基)-1,2,4,5-四嗪的程序。2,4-双[4-(4,5-二氢-1H-咪唑-2-基)苯氧基]嘧啶和2-氯-4-[4-(4,5-二氢-1H-咪唑- 2-基)-苯氧基嘧啶举例说明了标题合成中间体的使用。
