Participants

Reaction Steps

N-[(1-{4-[4-(3-tert-Butyl-ureido)-phenyl]-cyclohexyl}-azetidin-3-ylcarbamoyl)-methyl]-3-trifluoromethyl-benzamide (prepared as described in Example 18, 50 mg, 0.087 mmol) was treated with TFA (1 mL) at room temperature overnight. The reaction was quenched with saturated NaHCO3. The reaction solution was extracted with a chloroform/IPA “cocktail” (˜3:1, v/v). The organic layer was dried over anhydrous Na2SO4, filtered and concentrated to give the crude product, which was then 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 two title compound as white solid.
