Reaction Steps

To a mixture of (S)-(+)-2,2-dimethylcyclopropane carboxylic acid (2.39 mg, 0.021 mmol) and ((S)-1-{(S)-2-[4-(4′-{[6-((2R,5S)-2,5-dimethyl-piperazin-1-yl)-pyridine-3-carbonyl]-amino}-2,2′-dimethyl-biphenyl-4-yl)-1H-imidazol-2-yl]-pyrrolidine-1-carbonyl}-2-methyl-propyl)-carbamic acid methyl ester tri-TFA (20 mg, 0.019 mmol, Preparation 30) in DMF (0.5 mL, 6 mmol) at RT was added HATU (7.98 mg, 0.021 mmol) followed by N,N-diisopropylethylamine (16.60 uL, 0.095 mmol). The reaction mixture was stirred at RT overnight, concentrated, dissolved in 1:1 acetic acid:water (1.5 mL), filtered, and purified by preparative HPLC to provide the di-TFA salt of the title compound (15 mg).
