Reaction Steps
Into a 500 mL round bottom flask were combined (7-nitro-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazin-3-yl)methanol (0.320 g, 0.00152 mol), 10%-palladium on carbon (0.06 g, 0.0005 mol) and methanol (50 mL). The apparatus was evacuated, then hydrogen was introduced and the mixture was allowed to stir overnight (at 1 atm presuure). The mixture was then filtered through celite and the filtrate was concentrated under vacuum to yield an oil (0.252 g, 89%) which was used directly in the next step without further purification. (0.252 g, 89%) LC-MS 0.29 min. M/Z=181.9 (M+1).
