Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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 2-(benzylsulfanyl)-1-ethanamine hydrochloride (44 mg, 0.22 mmol) according to Method C with HPLC purification to give the title compound (15 mg). 1H-NMR (400 MHz, CD3OD) d 7.76 (s, 1H), 6.97 (d, J=8.6 Hz, 1H), 4.77 (s, 2H), 4.51 (m, 1H), 4.24 (dd, J=5.1 Hz, J=9.3 Hz, 1H), 3.71 (s, 2H), 3.19 (m, 1H), 2.74 (m, 1H), 2.41 (m, 2H), 1.35 (s, 9H); HRMS m/z 679.2542 (calc. of monoisotopic mass for C34H41N3O9S gives 679.2564). Synthesis according to Method C with HPLC purification
