2-Fluoro-N-{[1-(4-phenyl-cyclohexyl)-azetidin-3-ylcarbamoyl]-methyl}-5-trifluoromethyl-benzamide (as prepared in Example 66, 50 mg, 0.11 mmol) was treated with dimethyl amine (Aldrich, 40 wt. % in water, ˜2 mL) in a sealed tube under microwave irradiation at 120° C. for 20 min. The solvent was removed and the residue was purified on a silica gel column using 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 title compound as a white solid.
