A series of N-substituted carbamates V-XIII was prepared by reactions of 6,11-dihydrodibenzo[b,e]thiepin-11-ol (I) with carbamates H2NCOOR in acetic acid. Whereas the Leuckart reaction of dibenzo[b,e]thiepin-11(6H)-one yielded 9-formamido-10-methylene-9,10-dihydroanthracene (XVIII), a satisfactory method for preparing the amine III was found in heating the carbamate V with 2-aminoethanol to 170°C. Reactions of the amine III with isocyanates gave most of the disubstituted ureas XX-XXV. The expected anticonvulsant activity was found only in high doses with compounds IX, XII, XV, XX, XXI and XXXIII.
一系列N-取代的氨甲酸酯V-XIII通过在乙酸中6,11-二氢二苯并[be]噻吩-11-醇(I)与氨甲酸酯H2NCOOR反应而制备。而二苯并[be]噻吩-11(6H)-酮的Leuckart反应产生了9-甲酰基-10-亚甲基-9,10-二氢蒽(XVIII),在加热氨甲酸酯V与2-氨基乙醇至170°C的条件下找到了制备胺III的满意方法。胺III与异氰酸酯反应产生了大部分的二取代脲XX-XXV。预期的抗癫痫活性仅在化合物IX、XII、XV、XX、XXI和XXXIII中高剂量下发现。
