Reaction Steps

The quinolinone (30g), hydroxylamine hydrochloride (14g), sodium hydroxide (9g), ethanol (165ml) and water (65ml) were stirred and refluxed for 2 hours. Water (100 ml) was added and the product was allowed to crystallise overnight. The crystals were removed by filtration and washed with water and dried to give 3-methyl-8-oximino-5,6,7,8-tetrahydroquinoline (27.5g) mp 188° C.
