The invention relates to an improved method for the solution phase synthesis of Lanreotide acetate (1) comprising coupling of two suitably protected tetrapeptide fragments wherein the threonine hydroxyl is protected, to give an octapeptide, which on deprotection, oxidation, followed by treatment with acetic acid provides Lanreotide acetate (1) having desired purity.
