A process for preparing a dibenzothiazepine derivative such as dibenzo[b,f] [1,4]thiazepin-11-one employable as a starting material for the preparation of 11-[4-(2-(2-hydroxyethoxy)ethyl)]-1-piperadinyldiberizothiazepine derivative which is known to be effective as an antipsychotic pharmaceutical, has the steps of reacting a nitrobenzene derivative with a thiosalicylic acid derivative, reducing the obtained 2-nitro-2'-carboxy-diphenylsulfide derivative, and subjecting the obtained 2-amino-2'-carboxy-diphenylsulfide derivative to dehydration-condensation reaction.
一种制备二苯并硫氮杂卓衍生物如二苯并[b,f][1,4]硫氮杂卓-11-酮的工艺,可用作制备 11-[4-(2-(2-羟基乙氧基)乙基)]-1-哌啶基二苯并硫氮杂卓衍生物的起始原料,该衍生物已知可有效地用作抗精神病药物、其步骤包括使硝基苯衍生物与硫代水杨酸衍生物反应,还原得到的 2-硝基-2'-羧基-二苯硫醚衍生物,并使得到的 2-氨基-2'-羧基-二苯硫醚衍生物进行脱水缩合反应。
