A trifluoroacetic acid (TFA) labile protecting group for the guanidine side chain function of arginine has been developed. NG-(2,2,5,7,8-Pentamethylchroman-6-sulphonyl-L-arginine is cleaved rapidly in TFA or 50% TFA in dichloromethane at room temperature. The preparations of Fmoc.Arg(Pmc).OH and Bnpeoc.Arg(Pmc).OH are described.
