previously reported 3-isomer. This material was converted to the 1-cyano derivative and cyclized with chloroformamidine hydrochloride to [l]benzothieno-[3,2-f]quinazoline-1,3-diamine. Both this and the corresponding 7,7-dioxide were devoid of antimalarial activity.
已证明2-二苯并噻吩苯胺的溴化可提供1-溴-2-二苯并噻吩苯胺而不是先前报道的3-异构体。将该物质转化为1-氰基衍生物,并用氯甲酸am盐酸盐环化为[1]苯并噻吩并- [3,2 - f ]喹唑啉-1,3-二胺。这和相应的7,7-二氧化物都没有抗疟活性。
