8-hydroxy-10,10-dimefhyl-10H-pyrido[1,2-a]indol-6-ones 4, which were halogenated in position 7, 8 and 9 with sulfuryl chloride, bromine or phosphoroxychloride to give the corresponding halo-10,10-dimethyl-10H-pyrido[1,2-a]indoles 5, 6, 7 and 8. Amination affords the 8-amino-10,10-dimethyl-10H-pyrido[1,2-a]indol-6-one 9. Nitration gives either the 10,10-dimethyl-7-nitro-10H-pyrido[1,2-a]indoles 10 or 10,10-dim
2,3,3-三甲酰基-3 H-吲哚2与丙二酸酯3的环缩合得到8-羟基-10,10-二甲酰基-10 H-吡啶并[1,2- a ]吲哚-6-ones 4,它们被卤化了。在与磺酰氯,溴或磷酰氯位置7,8和9,得到相应的卤代-10,10-二甲基-10- ħ -吡啶并[1,2-一个]吲哚5,6,7和8。胺化得到8-氨基-10,10-二甲基-10 H-吡啶基[1,2 - a ]吲哚-6-1 9。硝化产生10,10-二甲基-7-硝基-10 H-吡啶基[1,2- a根据条件,吲哚10或10,10-二甲基-7-羟基-10 H-吡啶并[1,2- a ]吲哚11。
