To a solution of 1-(1-(4-(4-piperidinyloxy)-2-(2,2,2-trifluoroethoxy)phenylacetyl)piperidin-4-yl)-4H-3,1-benzoxazin-2(1H)-one hydrochloride (0.20 g, 0.35 mmol) from Example 2 in CH2Cl2 (20 mL) was added dimethylcarbamoyl chloride (0.042 g, 0.39 mmol) and DIEA (0.14 mL, 0.80 mmol). The solution was stirred at ambient temperature for 6 h and the solvent was removed under reduced pressure. The residue was dissolved in EtOAc (50 mL) and washed with 0.25 M aqueous citric acid (25 mL), H2O (25 mL), and saturated aqueous NaHCO3 (25 mL). The organic phase was dried (MgSO4), filtered, and the solvent was removed under reduced pressure. The residue was purified by pressurized silica gel column chromatography using 97:3 CH2Cl2 :MeOH as eluant to give the title compound as an amorphous solid.
