To a solution of tert-butyl 3-methyl-3-(methyl(1-methyl-2-oxo-8-(trifluoromethyl)-3-((2-(tri methylsilyl)ethoxy)methyl)-1,2,3,5-tetrahydrobenzo[5,6][1,4]oxazino[3,4-c][1,2,4]triazin-9-yl)amino)azetidine-1-carboxylate (0.586 g, 0.360 mmol) in DCM (4 mL) was added TFA (0.8 mL) and the mixture was stirred at ambient temperature for 1.5 h. The solvent was removed in vacuo and dioxane (1 mL) and ammonium hydroxide (25%, 1 mL) were added and the reaction mixture was stirred for 1.5 h at ambient temperature. The solvent was removed in vacuo and the residue was purified by HPLC (Table 3, Method 19) and further separated by chiral SFC (Table 2, Method 12) to give (R)-1-methyl-9-(methyl(3-methylazetidin-3-yl)amino)-8-(trifluoromethyl)-3,5-dihydrobenzo[5,6][1,4]oxazino[3,4-c][1,2,4]triazin-2(1H)-one trifluoroacetic acid (SFC (Table 1, Method 17) Rt: 6.57 min, 0.033 g, 7%)) as a pale solid. LC/MS (Table 1, Method 5) Rt=2.319 min.; MS m/z: 384 [M+H]+.
