To a solution of 4′-[((4,4-dimethylcyclohexyl){[(1,1-dimethylethyl)oxy]carbonyl}amino)-methyl]-3-biphenylcarboxylic acid (0.100 g; 0.23 mmol) in DMF (2 mL) was added DIEA (0.035 mL; 0.25 mmol), and HATU (0.095 g; 0.25 mmol). The solution was aged 5 min at room temperature and phenethylamine (0.031 mL; 0.25 mmol) was added. After 45 min the mixture was partitioned between EtOAc and half-satd Na2CO3, layers were separated and the aqueous layer was extracted with EtOAc (×2). Combined organics were washed (water, brine), dried over Na2SO4 and concentrated in vacuo. The residue was purified by flash chromatography (EtOAc/hexanes), affording the title compound as a colorless gum. LC/MS (method E) tR 1.19 min; m/z 541 (M+H).
