Participants

Reaction Steps

N-(t-butoxycarbonyl)-3-phenoxyphenylalanine (1 g) was dissolved in dry tetrahydrofuran (30 ml) and triethylamine (2 ml) was added thereto. Thereafter, ethyl chlorocarbonate (0.3 g) was added under ice-cooling, followed by stirring for 30 minutes. To this solution, 4-aminopyrimidine (0.24 g) was added, followed by stirring at room temperature for 10 hours. After distilling off the solvent, the residue was extracted with ethyl acetate, followed by washing with water. After drying, the solvent was distilled off to obtain N-(t-butoxycarbonyl)-3-phenoxy-DL-phenylalanine 4-pyrimidylamide (I) (1.5 g), which was confirmed as a substantially pure product by an NMR analysis, in the form of a white powder.
