{(3S,5S)-1-{(S)-2-[(S)-2-(tert-Butoxycarbonyl-methyl-amino)-propionylamino]-2-cyclohexyl-acetyl}-5-[(R)-(1,2,3,4-tetrahydro-naphthalen-1-yl)carbamoyl]-pyrrolidin-3-yl}-carbamic acid 9H-fluoren-9-ylmethyl ester → A 410099.1, amine-Boc

Participants

Reaction Steps

In a similar manner to that described for {(S)-1-[(S)-2-((2S,4S)-4-amino-2-benzylcarbamoyl-pyrrolidin-1-yl)-1-cyclohexyl-2-oxo-ethylcarbamoyl]-ethyl}-methyl-carbamic acid tert-butyl ester (Intermediate 28, Step 2), {(3S,5S)-1-{(S)-2-[(S)-2-(tert-butoxycarbonyl-methyl-amino)-propionylamino]-2-cyclohexyl-acetyl}-5-[(R)-(1,2,3,4-tetrahydro-naphthalen-1-yl)carbamoyl]-pyrrolidin-3-yl}-carbamic acid 9H-fluoren-9-ylmethyl ester (Intermediate 25) (500 mg, 0.62 mmol) was converted to the title compound (360 mg, foam).
