Abstract
in an organic solvent to obtain peptide-solid support of formula (4), cleaving and deprotecting all groups in the peptide of formula (4) from the solid support to obtain peptide-amide formula (5), oxidizing the SH-peptide of formula (5) with an appropriate oxidizing agent to obtain the crude peptide-amide of formula (1) and purifying the crude peptide-amide of formula (1) by chromatographic technique. The solid support is either resin or a cellulose support like cotton, gauze, fabric, paper and perloza beads. The described process is simple, easy, environment friendly, takes lesser time and more cost effective.
