The product from Example 143 Part D (90 mg, 0.51 mmol), Bop reagent (265 mg, 0.61 mmol), and triethylamine (0.42 mL, 1.5 mmol) were added together with 5 mL of THF. The mixture was stirred at RT under N2 for 15 minutes and (S)-4-(2-(1-amino-2-phenylethyl)-1H-imidazol-4-yl)benzamide prepared using the methods described in Examples 2 and 28 (365 mg, 0.51 mg) was added. The resulting mixture was heated at 75° C. for 70 minutes. The THF was removed, and the residue was dissolved in EtOAc. It was washed with waster and brine, dried over MgSO4, concentrated, and purified by flash chromatography (silica, EtOAc/hexane) to give 80 mg of the desired product. MS: 464.4 (M+1)+.
