The present invention relates to compounds of the formula
wherein R is methyl, fluorine or bromine,
and pharmaceutically acceptable salts thereof. Utilizable as therapeutically active agents especially for the treatment of retroviral infections, particularly HIV infections, they can be prepared in a manner known per se by a process which comprises reacting 2-bromo-2'-(1H-pyrrol-2-yl-carbonyl)acetanilide, correspondingly substituted by R in the 4'-position, with ammonia and cyclizing the obtained 2-aminoacetanilide with pivalic acid.
本发明涉及公式如下的化合物及其药学上可接受的盐:其中R为甲基、氟或溴,可作为治疗活性剂,特别是用于治疗逆转录病毒感染,尤其是HIV感染。它们可以按照已知的方法制备,该方法包括将2-溴-2'-(1H-吡咯-2-基)苯甲酰胺与对应于4'-位置中的R取代物反应,并用氨基酸环化所得的2-氨基乙酰苯胺与缬油酸反应。
