2-bromo-8-ergolinyl compounds of the formula ##STR1## wherein R.sup.8 is NH.sub.2, NH--CONEt.sub.2, CONH.sub.2, ##STR2## and ##STR3## wherein R.sup.1 =C.sub.1-4 -alkyl and R.sup.2 =C.sub.1-4 -alkyl and benzyl, R.sup.9 and R.sup.10 each mean hydrogen or, together, a bond, and the substituent R.sup.8 can be in the .alpha.- or .beta.- position, and their acid addition salts, can be prepared from corresponding 8-ergolinyl compounds and their acid addition salts by bromination with elemental bromine in the presence of hydrogen bromide in a halogenated hydrocarbon.
该公式为##STR1##的2-溴-8-麦角碱化合物,其中R.sup.8为NH.sub.2、NH--CONEt.sub.2、CONH.sub.2、##STR2##和##STR3##,其中R.sup.1=C.sub.1-4-烷基,R.sup.2=C.sub.1-4-烷基和苄基,R.sup.9和R.sup.10分别表示氢原子或者一起表示一个键,取代基R.sup.8可以在α-或β-位置,其酸加成盐可以通过在卤代烃中加入溴素和氢溴酸的情况下,从相应的8-麦角碱化合物及其酸加成盐制备而成。
