Reaction Steps

To a solution of 120 mg of t-butyl 2-methyl-3,4,6,7,9,10-hexahydro[1,4]oxazino[2,3-h][3]benzazepine-8(2H)-carboxylate in 4 ml of DMF were added 0.026 ml of methyl iodide and 104 mg of potassium carbonate at room temperature, followed by stirring for 13 hours. To the reaction mixture were added 0.012 ml of methyl iodide and 26 mg of potassium carbonate, followed by further stirring for 3 hours. To the reaction mixture was added water, followed by extraction with EtOAc twice. The combined organic layer was washed with saturated brine, dried over anhydrous sodium sulfate, and then filtered, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel chromatography (elution solvent: HEX-EtOAc) to obtain 55 mg of t-butyl 2,4-dimethyl-3,4,6,7,9,10-hexahydro[1,4]oxazino[2,3-h][3]benzazepine-8(2H)-carboxylate as a brown solid.
