As part of our study of potential atypical antipsychotic agents,] the synthesis of 3-methyl-6chloromethyl benzothiazolin-Zone (4a) and benzoxazolin-Zone (4b) previously prepared by Carato et al., I was reported as shown in Scheme 1. The 3-methyl derivatives (la and lb) were formylated using hexamethylenetetramine in polyphosphoric acid (PPA),2.3 to give compounds 2a and 2b which were then reduced to
作为我们对潜在非典型抗精神病药物研究的一部分,] Carato 等人先前制备的 3-甲基-6 氯甲基苯并噻唑啉-区 (4a) 和苯并恶唑啉-区 (4b) 的合成,如方案 1 所示。 3-甲基衍生物(Ia和Ib)在多磷酸(PPA)2.3中使用六亚甲基四胺甲酰化,得到化合物2a和2b,然后将其还原为相应的醇3a和3b。在无水氯仿中使用 SOCI 将羟基转化为相应的氯类似物 4s 和 4b。本文描述了 6-氯甲基苯并噻唑啉-2-one (13a) 和苯并恶唑啉-2-one (13b) 的合成,这些都是制备潜在抗精神病药物所需的。
