Procedure

A solution of 1-(4′-{4-[(1-benzyl-1H-[1,2,3]triazol-4-yl)-hydroxy-methyl]-3-methyl-isoxazol-5-yl}-biphenyl-4-yl)-cyclopropanecarboxylic acid (Enantiomer B) (0.100 g, 0.197 mmol), carbonyldiimidazole (0.080 g, 0.5 mmol), N,N-dimethylamino pyridine (0.002 g, 0.02 mmol) in THF (2 mL) was stirred at room temperature overnight. Added MeSO2NH2 (0.050 g, 0.5 mmol) and DBU (0.100 mL, 0.65 mmol) and the mixture heated to 100° C. in a capped vial for 4.5 hours. The solution was poured into sat. aqueous NH4Cl, then water and EtOAc was added. The organic layer was separated, dried (Na2SO4), concentrated and the resulting reside purified by preparative HPLC to yield the title compound.
