发明名称 PROCESS FOR PREPARING HETEROCYCLIC COMPOUND CONTIANING NITROGEN
摘要 After the compd. (II, R=H, OH, alkoxy, halogen; R1=H, lower alkoxy; R2=nitrile, acetyl) was bromided by solid bromination agents such as N-bromophthalimide, N-bromosuccnimide, N-bromoacetamide and 1, 3-dibromo-5, 5-dialkylhydantoin at the temp. of 25-100≦̸C, the reactant was added to tertiary organic salts such as triethylamine, pyridine, N-methylmorpolin and N,N-dimethylbenzylamine to give final compound(I).
