3-chloropropionyl chloride to give the corresponding chloropropionyl derivatives (III) and (IV), respectively. Analogously, (II) and 4-chlorobutyry! chloride gave the compound (V). These N-~-chloroacyl derivatives of the starting materials gave on reaction with secondary bases a series of corresponding amino derivatives (VI), (VII), (VIII), and (IX). Alkylation of (II) with 2-dimethylaminoethyl, 3-dimethylaminopropyl
1,2,3,4-四氢苯并呋喃E3,2-~]吡啶(1)及其4-甲基同系物(II),均由我们之前描述过[5],在氮原子上用3-氯丙酰氯酰化得到分别为相应的氯丙酰基衍生物 (III) 和 (IV)。类似地,(II) 和 4-氯丁酸!氯化得到化合物(V)。原料的这些N--氯酰基衍生物与仲碱反应得到一系列相应的氨基衍生物(VI)、(VII)、(VIII)和(IX)。(II)与2-二甲氨基乙基、3-二甲氨基丙基和3-N'-甲基哌嗪丙基氯化物的烷基化分别得到二胺(X)和(XI)以及三胺(XII)。化合物(XIII)和(XIV)分别由(I)和(II)通过用3-对-氟苯甲酰丙基氯处理(见表i)获得。
