Abstract
This article studied the synthesis of Fmoc-Arg(Pbf)-OH.Adding phase-transfer catalyzer tetraethyl ammonium bromide(TEBA)during the introduction of Pbf protecting group,the reaction proceeded more rapidly and the hydrolyzation of Pbf-Cl was reduced.Putting cyclohexylamine into the solution of Cbz-Arg(Pbf)-OH during the formation of salt increased the quality.The yield was increased from 59% to 72%.
