The mixture was stirred for 2 h, during which the temperature was allowed to rise from -5 to 20 C. The organic phase was washed with water, 5% strength sodium bicarbonate and 5% strength citric acid solutions, dried over Na2SO4 and evaporated to dryness. A pale yellowish crystalline residue was obtained and was used without further purification in the next reaction.

With 4-methyl-morpholine; In hexane; water; ethyl acetate; N,N-dimethyl-formamide; a Boc-D-Phenylalanylproline (p-cyanobenzyl)amide 2.0 g (14.6 mmol) of isobutyl chloroformate were added in 2 min to a solution of 5.1 g (14.2 mmol) of <strong>[38675-10-4]Boc-D-Phe-Pro-OH</strong> and 1.53 g (15.2 mmol) of N-methylmorpholine in 15 ml of DMF at -15 C., the mixture was stirred for 10 min and then a solution of 1.9 g (14.2 mmol) of p-cyanobenzylamine (W. Walter et al., Ann. 660, 1962, 60) and 1.53 g of N-methylmorpholine in 3 ml of DMF was added. After stirring at -15 C. for 3 h, a TLC check (CH2 Cl2 /MeOH, 9/1) showed no detectable starting compounds. For isolation, the reaction mixture was poured into 200 ml of water, when an oil separated out and, after a short time, solidifed and was broken up and filtered off with suction. The still moist residue was dissolved in a mixture of 250 ml of ethyl acetate and 50 ml of ether and washed successively with a 5% strength aqueous citric acid, bicarbonate and saturated sodium chloride solutions. After drying over Na2 SO4, the solvent was removed by distillation under reduced pressure, and the residue was mixed with n-hexane and then filtered off with suction. Recrystallization from 50 ml of ethyl acetate afforded 5.6 g of TLC-pure product, m.p. 156-157 C.

YieldReaction ConditionsOperation in experiment
64% With 4-methyl-morpholine; benzotriazol-1-ol; 1-ethyl-(3-(3-dimethylamino)propyl)-carbodiimide hydrochloride; In N,N-dimethyl-formamide;pH 8.0; To the solution of <strong>[38675-10-4]Boc-D-Phe-L-Pro-OH</strong> (580 mg, 1.60 mmol) and 4,5,6,7-tetrahydro-1,3-benzothiazole-2,6-diamine dihydrobromide (482 mg, 1.46 mmol) in 3.7 mL of N,N-dimethylformamide was added HOBt (247 mg, 1.60 mmol). N-Methylmorpholine was used to set pH of the solution to 8 and EDC (313 mg, 1.60 mmol) was added. The reaction mixture was stirred overnight, the solvent was evaporated in vacuo and the residue partitioned between EtOAc and saturated solution of NaHCO3. Organic layer was washed with brine dried with MgSO4, filtered and the solvent was evaporated under reduced pressure. The crude product was purified with column chromatography (silicagel, CHCl3/MeOH=9/1) to yield 480 mg of faint brown crystalline solid (64%). Melting point: 120-123 C. IR (KBr): ν=3418, 2975, 1646, 1523, 1448, 1367, 1252, 1167, 860, 752, 702 cm-1. MS (FAB): m/z (%) 514 (MH+, 59/2.50), 70 (100).
