3-piperidin-4-yl-4H-1,3-benzoxazin-2-one;hydrochloride

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

実験手順: In this reference example, 16.0 g of 1-benzyl-4-(2-oxo-3,4-dihydro-2H-1,3-benzoxazin-3-yl)-piperidine and 4.0 g of 10% palladium carbon are added to a mixture of 150 ml of water, 50 ml of 1 N hydrochloric acid and 300 ml of methanol. While the resultant mixture is stirred, hydrogen gas is passed therethrough overnight. Then, the reaction mixture is filtered and the filtrate is concentrated. The white crystals as a residue are mixed with methanol and separated by filtration to obtain 11.4 g of the desired product. overnight Then, the reaction mixture is filtered the filtrate is concentrated The white crystals as a residue are mixed with methanol separated by filtration
