Reaction Steps

A solution of [4-(4-{3-[2-(3-trifluoromethyl-benzoylamino)-acetylamino]-azetidin-1-yl}-cyclohexyl)-phenyl]-acetic acid (as prepared in Example 25, 450 mg, 0.87 mmol), EDCI (240 mg, 1.25 mmol), HOBT (130 mg, 0.96 mmol) and TEA (610 μL, 4.35 mmol) in DCM (10 mL) was treated with 2N NH3 in dioxane (5 mL) at room temperature overnight. The solvent was removed in vacuo and the residue was purified by a CombiFlash® system using ethyl acetate and 7N NH3 in MeOH as eluent (from pure ethyl acetate to 5% 7N NH3 in MeOH in ethyl acetate) to afford the two title compound as white solids.
