초록
An efficient, chemoselective and practical protocol for N-Boc protection of amines using di-tertbutoxypyrocarbonate (Boc)2O in presence of Indion 190 resin. Resin was easily separated from the reaction mixture by filtration and reused in subsequent reactions without any apparent loss of activity. Simple workup, mild condition, short reaction time and high yield are some of the striking features of the present process.
