Abstract:Using ethanolamine and benzyl chloride as the raw materials, the pharmaceutical intermediate N,N',N'',N'''-tetrabenzylcyclene was synthesized in a four-step continuous reaction, the product structure was confirmed by IR, 1H NMR, 13C NMR and HRMS. There was no requirement for separation and purification of the intermediates including N-benzylethanolamine, N-benzylethanolamine sulfonate and N-benzylethanolamine. A total yield of the whole four steps reaction was up to 35.5%.
Key words:N,N',N'',N'''-tetrabenzylcyclene; N-benzylaziridine; N-benzylethanolamine sulfonate; N-benzylethanolamine; continuous process
