Reaction Steps

A 9 g quantity of the 2-[2-(3-benzyloxy-4-methoxyphenyl)oxazol-4-ylmethyl]isoindolin-1,3-dione obtained in Reference Example 6 was suspended in 200 ml of ethanol, and 3.1 ml of hydrazine monohydrate was added. The mixture was heated and refluxed for 3 hours. After cooing the reaction mixture, 200 ml of dichloromethane was added and the mixture was stirred. Insolubles were removed by filtration, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (NH silica, product of Fuji Sylisia Chemical Ltd., dichloromethane:methanol=20:1) to give 4.5 g of pale yellow powdery [2-(3-benzyloxy-4-methoxyphenyl)oxazol-4-yl]methylamine.
