6-chlorobenzo[b][1,4]benzoxazepine

反応条件: temp:90.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of 1 (229 mg, 1.00 mmol) in DME (3 mL) was added 4-methoxycarbonylphenylboronic acid (216 mg, 1.20 mmol), Pd(PPh3)4 (0.065 mg, 0.056 mmol) and 2 N Na2CO3(aq) (1.5 mL, 3.0 mmol). The reaction mixture was stirred for 2 h at 90° C. The solution was then cooled at room temperature and poured into AcOEt. The organic layer was washed with water, brine and dried (Na2SO4), filtered and concentrated to give a yellow oil. The residue was purified by silica gel column chromatography with EtOAc (15%) in Hexanes to afford 2 (327 mg, 99%) as a yellow foam. LRMS (ESI): (calc) 329.1. (found) 330.3 (MH)+. The solution was then cooled at room temperature The organic layer was washed with water, brine dried (Na2SO4) filtered concentrated to give a yellow oil The residue was purified by silica gel column chromatography with EtOAc (15%) in Hexanes

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A solution of 10,11-dihydrodibenz[b,f][1,4]oxazepin-11-one (1.00 g, 4.74 mmol) and phosphorus oxychloride (40 mL) was stirred for 5 h at reflux. The reaction mixture was then cooled to room temperature and concentrated under reduced pressure. The residue was dissolved into AcOEt and washed with water and brine. The organic layer was dried (Na2SO4), filtered and concentrated to give an orange oil. The residue was purified by silica gel column chromatography with EtOAc (10%) in Hexanes to afford 1 (939 mg, 86%) as a yellow solid. LRMS (ESI): (calc) 229.0. (found) 230.1 (MH)+. at reflux concentrated under reduced pressure The residue was dissolved into AcOEt washed with water and brine The organic layer was dried (Na2SO4) filtered concentrated to give an orange oil The residue was purified by silica gel column chromatography with EtOAc (10%) in Hexanes
