Step X (3): trans-3-(allyloxy)-6-methoxy-2,3-dihydro-1H-inden-1-amine from Step X (2) was reacted with benzyl (S)-2-(3,5-difluorophenyl)-1-((S)-oxiran-2-yl)ethylcarbamate according to the conditions described in Step V (1). The crude product was purified using silica gel column chromatography to provide 900 mg (69% yield) of a mixture of benzyl (2S,3R)-4-((1S,3S)-3-(allyloxy)-6-methoxy-2,3-dihydro-1H-inden-1-ylamino)-1-(3,5-difluorophenyl)-3-hydroxybutan-2-ylcarbamate and benzyl (2S,3R)-4-((1R,3R)-3-(allyloxy)-6-methoxy-2,3-dihydro-1H-inden-1-ylamino)-1-(3,5-difluorophenyl)-3-hydroxybutan-2-ylcarbamate.
