반응 단계

To a solution of tert-butyl (2R,5R)-5-(aminomethyl)-2-[2-(2-{[N-(methoxycarbonyl)-β-phenyl-L-phenylalanyl]amino}phenyl)ethyl]morpholine-4-carboxylate (1 eq.) in CH2Cl2 (0.4M) was added copper(II) sulfate (0.02 eq.) and sodium bicarbonate (1 eq.) as a solution in water (NaHCO3/CuSO4)) (1M). To that mixture was added triflic azide (3.65 eq.) as a solution in CH2Cl2 (0.4M). The heterogenous mixture was homogenized by the addition of methanol and the reaction was stirred at room temperature for 30 minutes. Upon completion by LCMS, solvents were evaporated and the evaporation residue was used as such for next step.
