Reaction Steps
To a suspension of 1.2 g (2.5 mmol) of phthalimide 4 in 100 ml of methanol was added 6 ml of hydrazine monohydrate. This was stirred at room temperature overnight upon which the suspension turned into a clear yellow solution. The mixture was concentrated and residue was diluted with water and extracted with chloroform. The organic solution was washed with brine and dried (MgSO4), and the residue was purified by column chromatography with silica eluting with 10% methanol in dichloromethane affording 0.48 g of the aminoethyl-pyridone 5 (55% yield).
