Reaction Steps

Following a procedure analogous to that for the synthesis of Compound E of Example 22, (S)-2-tert-butyl 3-methyl 7-((S)-1-(tert-butoxycarbonyl)-5-(((R)-1,2,3,4-tetrahydronaphthalen-1-yl)carbamoyl)-2,5-dihydro-1H-pyrrol-3-yl)-3,4-dihydroisoquinoline-2,3(1H)-dicarboxylate (730 mg, 1.16 mmol) was converted to the title compound (650 mg, 89%). MS (ESI+) m/z 634.5 (M+H)+.
