실험 절차

1.25 g (9.2 mmol) of 2-amino-1,4,5,6-tetrahydropyrimidine hydrochloride and 1.03 g (9.2 mmol) of potassium tert-butoxide were dissolved in 3 ml of absol. DMF and the mixture was stirred at RT for 30 min. 740 mg (1.53 mmol) of tert-butyl (2S)-2-benzyioxycarbonylamino-3-(4-(2-methoxycarbonylethyl)benzoylamino)propionate (Example 3c) in 1 ml of DMF were then added and the mixture was stirred at RT for 4h. It was adjusted to pH 4 using glacial acetic acid, the solvent was stripped off in vacuo, and the residue was chromatographed on silica gel (dichloromethane/methanol/glacial acetic acid/water (9/110.1/0.1)).
