To a solution of N-(3-((4S,6S)-2-benzamido-4-methyl-6-(trifluoromethyl)-5,6-dihydro-4H-1,3-oxazin-4-yl)-4-fluorophenyl)-4-methoxypiperidine-1-carboxamide (0.166 g, 0.309 mmol) in MeOH (3 mL) at room temperature was added 1,8-diazabicyclo-[5.4.0]undec-7-ene (0.100 mL, 0.669 mmol). The reaction was heated at 60° C. for 4 h. Then the reaction was cooled to room temperature, diluted with MeOH, purified by reverse-phase HPLC (Gilson; Gemini-NX 10m C18 110A AXIA, 100×50 mm column) eluting with 0.1% TFA-H2O:0.1% TFA CH3CN (9:1→1:9). The fractions containing the desired product were combined and concentrated in vacuo. The material was dissolved in MeOH and eluted with MeOH, through an Silicycle carbonate cartridge to give the titled compound as a white crystalline solid (68 mg, 51%). MS m/z=433 [M+H]+. Calculated for C19H24F4N4O3: 432
