-
Paragraph 0038-0041, (2019/07/04)
The invention discloses a phenylethanolamine β receptor agonist synthetic method, comprises the following steps: S1: the 4 - amino acetophenone dissolved in an organic solvent, with the electrophilic reagent occurs on the benzene ring substituted halogenated reaction, generating [...] intermediate; [...] intermediates in organic solvent or in water, under the catalysis of the metal catalyst with the cyanide reagent undergo nucleophilic substitution reaction, generating phenyl ketone intermediate; S2: phenyl ketone intermediates in organic solvent, with the copper bromide generating carbonyl α bromo reaction to produce α - bromoacetophenone intermediates; S3: α - bromoacetophenone intermediates in organic solvent with tert-butyl amine or isopropylamine reaction intermediates acetophenone amines; S4: acetophenone amine intermediates in organic solvent, with the reduction hydrogenation reagent react to generate the phenylethanolamine β receptor agonists; synthetic method of this invention a simple and highly efficient and cheap and easy to obtain, atom utilization is high, the synthetic product chemical purity is greater than 99%, to meet the detection requirements of the food safety.
