Participants

Reaction Steps

Synthesis was performed from (2S)-2-({(2S)-2-[(tert-butoxycarbonyl)amino]-3-phenylpropanoyl}amino)-3-[3-(methoxycarbonyl)-4-(2-methoxy-2-oxoethoxy)phenyl]propanoic acid (100 mg, 0.18 mmol) and N-(2-aminoethyl)-pyrrolidinone (33 mg, 0.29 mmol) according to Method C with HPLC purification to give the title compound (10 mg). 1H-NMR (400 MHz, CD3OD) δ 1.36 (s, 9H) 2.05 (s, 4H) 2.68-3.20 (m, 8H) 3.39 (m, 4H) 4.28 (m, 1H) 4.39 (m, 1H) 4.69 (s, 2H) 7.05-7.40 (m, 7H) 7.52 (s, 1H); HRMS m/z 626.2929 (calc. of monoisotopic mass for C32H42N4O9 gives 626.2952).
