摘要:
The present invention relates to 6-([1,2,4]triazolo[4,3-b]pyridazin-6- yl)-7,8-dihydro-5H-1,6-naphthyridine derivatives, 6-(imidazo[1,2- b]pyridazin-6-yl)-7,8-dihydro-5H-1,6-naphthyridine derivatives or 6- (imidazo[1,5-b]pyridazin-6-yl)-7,8-dihydro-5H-1,6-naphthyridine derivatives of formula (I) The present compounds are positive allosteric modulators of the muscarinic acetylcholine receptor M4 (mAChR M4) for use in treating neurological and psychiatric disorders associated with muscarinic acetylcholine receptor dysfunction. An exemplary compound is e.g. compound 1 Data on the activity of exemplary compounds in an mAChR M4 cell- based assay is provided.
reactivity towards electrophilic substitutions are reported. The nitration was shown to be very dependent on the nature of the 2 substituent. Nitrosation using sodium nitrite in acetic acid media as a general method failed in all cases whereas chlorination was observed in warm hydrochloric acid. In order to ascertain the structure of some chloro derivatives, chlorination using N-chlorosuccinimide was
报道了2-取代的咪唑并[1,2- b ]哒嗪的合成及其对亲电子取代的反应性。已证明硝化非常依赖于2个取代基的性质。在所有情况下,使用亚硝酸钠在乙酸介质中进行亚硝化作为一般方法均失败,而在温暖的盐酸中观察到了氯化作用。为了确定某些氯衍生物的结构,使用N进行氯化还报道了-氯琥珀酰亚胺。根据取代基的性质,反应发生在C-3咪唑位置和/或位置2的取代基上。最后,使用另一种合成途径,通过3的直接缩合获得3-亚硝基-2-苯基衍生物。 -氨基-6-氯哒嗪成ω-氯-ω-亚硝基苯乙酮。使用高场1 H和13 C-NMR确定结构测定。
