3,5-Dichloro-2-iodobenzoic acid (IV), prepared from 3,5-dichloroanthranilic acid (III), was transformed in 5 steps into the diphenyl sulfide-2-acetic acids IXab. Cyclization resulted in ketones XVab which were processed in further 3 steps into the title compounds Iab and IIa. These products are mild tranquilizers devoid of cataleptic and antiapomorphine activity.
3,5-二氯-2-碘苯甲酸(IV),由3,5-二氯蒽酰氨酸(III)制备而成,经过5个步骤转化为二苯基硫醚-2-乙酸(IXab)。环化反应产生酮(XVab),经过另外3个步骤处理后得到标题化合物(Iab和IIa)。这些产品是温和的镇静剂,不具有强直和抗吗啡效应。
