Vorschrift

Step EE (1): (2R,3S)-1-((1S,3R)-3-(Allyloxy)-6-bromo-2,3-dihydro-1H-inden-1-ylamino)-3-amino-4-(3,5-difluorophenyl)butan-2-ol from Step EA (1) was coupled with hex-5-enoic acid by following a procedure analogous to Step EA (2) to afford 1.9 g (62% yield) of N-((2S,3R)-4-((1R,3R)-3-(allyloxy)-6-bromo-2,3-dihydro-1H-inden-1-ylamino)-1-(3,5-difluorophenyl)-3-hydroxybutan-2-yl)hex-5-enamide.
