Reaction Steps

A mixture of 4.98 g (19.5 mmole) of 1-(2-acetyl-3-fluoro-6-nitrophenoxy)-2-propanone, 100 ml of 95% ethanol and 1 g of Raney nickel was shaken in an atmosphere of hydrogen at 4.5×105Pa at room temperature for 18 hours. The reaction was filtered and the solvent removed at reduced pressure. The residue was chromatographed on silica, with hexane:ether (1:1) to give 2.76 g of 1-(7-fluoro-3,4-dihydro-3-methyl-2H-1,4-benzoxazin-8-yl)ethanone.
