Procedure:
Next, 31.3 g (0.08 mole) of H-Arg(NO2)-CHA.HCl was dissolved in 160 ml of 1.5N-NEM/DMF, to this solution was added 31.0 g (0.08 mole) of BOC-Phe-SDP (dimethylmercaptopyrimidine) at 0° to 5° C. and reacted for 18 hours. After the reaction was completed, the reaction mixture was diluted with 1600 ml of AcOEt, and washed twice with 400 ml of cold 5% hydrochloric acid, and washed twice with 400 ml of an aqueous solution saturated with sodium chloride, then there was precipitated crystals. The crystals thus precipitated were collected by filtration and dried to obtain crude BOC-Phe-Arg(NO2)-CHA, then recrystallized from AcOEt/n-hexane to obtain 35.1 g (72.9%) of BOC-Phe-Arg(NO2)-CHA.

After the addition was complete, the reaction mixture was heated to 100° C. where it stirred overnight. At this time, the reaction mixture was cooled to 25° C. and concentrated in vacuo. The residue was diluted with dichloromethane (100 mL) and was washed with a 2N aqueous hydrochloric acid solution (1×100 mL), a saturated aqueous sodium bicarbonate solution (1×100 mL), a saturated aqueous sodium chloride solution (1×100 mL), dried over magnesium sulfate, filtered, rinsed with dichloromethane and concentrated in vacuo.
