About 50 grams of resin beads of polystyrene that has been copolymerized with about 1% divinylbenzene are stirred at room temperature for about 2 hours in butyryl chloride with aluminum chloride as a catalyst, namely Friedel-Crafts conditions. Reaction occurs with the benzene moieties on the resin to form butyrophenone or propylphenylketone. These resulting ketone moieties are then subjected to the Leukardt-Wallach reduction amination reaction using N-propyl formamide to produce N-propyl α-aminobenzyl moieties. The step-by-step synthesis of the nonapeptide as set forth in Example I is repeated. Cleavage, deprotection and purification are carried out under the same conditions and are found to produce the nonapeptide amide having the following formula:
