Reaction Steps

4-(3-(Cyclopropylmethyl)ureido)benzoic acid (0.213 mmol, 0.05 g), methyl 4-(4-(1,1,1,3,3,3-hexafluoro-2-hydroxypropan-2-yl)benzyl)piperazine-2-carboxylate (0.213 mmol, 0.085 g) and triethylamine (0.640 mmol, 0.089 mL, 0.065 g) were combined and stirred in dichloromethane. 1-Propanephosphonic acid cyclic anhydride (0.320 mmol, 0.191 mL, 0.204 g) was added and the reaction stirred for 2 hours at room temperature. This was washed with water and the resulting residue purified by acidic prep HPLC to afford the title compound (45 mg). MS (ESI) m/z 617.2 [M+H]+
