1,1-dimethylethyl [2-({[4-(hydroxymethyl)phenyl]carbonyl}amino)-4-(2-thienyl)phenyl]carbamate (140 mg, 0.50 mmol), BOP (440 mg, 0.99 mmol), 4-(2-{[ethoxy(methyl)phosphoryl]oxy}ethyl)benzoic acid (90 mg, 0.33 mmol), and DIPEA (0.17 mL, 0.99 mmol) were stirred in DMF (1.1 mL) at 60° C. for 72 hours. The mixture was then diluted with saturated NaHCO3 solution and extracted with EtOAc. The organic layers were then washed with brine, dried over Na2SO4 and concentrated in vacuo. Purification of the crude reaction mixture by MPLC (0-10% MeOH/DCM) resulted in the title compound as a yellow foam. MS cal'd 445 (MH+-Boc), exp 445 (MH+-Boc).
