Reaction Steps

The procedure of Example 14(a) was repeated, except that (2R)-2-amino-4-methyl-N-[2-oxo-8-(2-oxopyrrolidin-1-yl)-1-(thiophen-3-ylmethyl)-1,2,3,4-tetrahydroquinolin-3-yl]pentanamide (400 mg) and 2-(tert-butoxycarbonylamino)-2-methylpropanoic acid (215 mg) were used, whereby the title compound (510 mg) was yielded.
