実験手順: The title compound was prepared as described in the General Method 1 using 5 mmol of methyl acetoacetate, 5.5 mmol of NaH 60% dispersion in oil, 5.5 mmol of 1.6M n-butyl lithium in hexane, 5.5 mmol of butyrophenone and 14 mL of tetrahydrofuran. After addition of the ketone, the reaction was stirred for 90 minutes at 0° C. The reaction was poured into saturated NH4Cl solution and extracted with ethyl acetate. The organic layer was dried over MgSO4, concentrated, and the residue flash chromatographed using hexane/ethyl acetate 80/20 as eluent.

実験手順: 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: Reaction

実験手順: To a 0° C. solution of EtMgBr in Et2O (3.0M, 570 mL, Aldrich) was slowly added m-tolunitrile (102 mL, Aldrich). After stirring at r.t. for 19 hr., benzene (300 mL) was added and the resulting mixture was cooled to 0° C. HCl (6N, 600 mL) was then slowly added. The organic phase was separated, washed with 5% NaHCO3 and brine, dried (MgSO4) and evaporated to afford the desired ketone as a yellow liquid. To a 0° C. the resulting mixture was cooled to 0° C The organic phase was separated washed with 5% NaHCO3 and brine dried (MgSO4) evaporated
