摘要:
By alkylation of methyl-N-(4-hydroxyphenyl) carbamate with (chloroniethyl)oxirane in acetone in the presence of K2CO3 methyl-N-[4-(2,3-epoxypropoxy)phenyl]carbamate was prepared. The aminolysis of the latter effected by benzylamine, morpholine, piperidine, and pyrrolidine occurs in keeping with Krasusky rule to afford methyl-N-[4-(3-R-amino-2-hydroxypropoxy)phenyl]carbamates.
