Reaction Steps

To a solution of 4,6,6a,8,9,10a-hexahydro-10a-methyl-7H-indolo[3,4-gh][1.4]benzoxazine (85 mg, 0.37 mmol) in DMF (5 ml) were added potassium carbonate (255 mg, 1.9 mmol) and 1-iodo-2-phenoxyethane (99 mg, 0.4 mmol). The mixture was heated at 60° C for 24 hours. After completion of the reaction, the reaction mixture was added to a mixture of ice water and ethyl acetate. The organic layer was separated, washed with a saturated aqueous saline solution and dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure, and the residue was subjected to a silica gel column chromatography, eluting with n-hexane-ethyl acetate (2:1), to afford 59 mg (46%) of the title compound as an amorphous crystalline product.
