(R)-2-((tert-Butoxycarbonyl)amino)-2-methylbutanoic acid → tert-butyl (2R)-2-methyl-1-[(2R)-3-(1-methyl-1H-indol-3-yl)-1-oxo-1-[2-oxo-8-(2-oxopyrrolidin-1-yl)-1-(thiophen-3-ylmethyl)-1,2,3,4-tetrahydroquinolin-3-ylamino]propan-2-ylamino]-1-oxobutan-2-ylcarbamate

Participants

Reaction Steps

The procedure of Example 14(a) was repeated, except that (2R)-2-amino-3-(1-methyl-1H-indol-3-yl)-N-[2-oxo-8-(2-oxopyrrolidin-1-yl)-1-(thiophen-3-ylmethyl)-1,2,3,4-tetrahydroquinolin-3-yl]propanamide obtained in Example 8(b) (5.4 g) and (R)-2-(tert-butoxycarbonylamino)-2-methylbutanoic acid (2.4 g) were used, whereby the title compound (6.6 g) was yielded.
