Step EX (1): (S)-2-(N-methylhexanamido)hex-5-enoic acid (500 mg, 2.1 mmol) and (2R,3S)-N1-(3-(allyloxy)-6-phenoxy-2,3-dihydro-1H-inden-1-yl)-2-(tert-butyldimethylsilyloxy)-4-phenylbutane-1,3-diamine (1.2 g, 2.1 mmol, from Preparation BC) were coupled using a procedure analogous to Step CA (1) to afford 650 mg (40% yield) of (2S)-N-((2S,3R)-4-(3-(allyloxy)-6-phenoxy-2,3-dihydro-1H-inden-1-ylamino)-3-(tert-butyldimethylsilyloxy)-1-phenylbutan-2-yl)-2-(N-methylhexanamido)hex-5-enamide.
