반응 단계

1-Chloro-4-morpholino-2-naphthol (15.0 g;0.057 mol), prepared as described in 2(a) above, was dissolved in 10% aqueous potassium hydroxide (100 ml) and was treated in the presence of palladium on charcoal (1.75 g;5%) at room temperature under 3 atmospheres of hydrogen until a stoichiometric amount of hydrogen was absorbed (approximately 24h). The palladium catalyst was removed by filtration and the filtrate neutralised with glacial acetic acid to afford 4-morpholino-2-naphthol as a white solid (8.5 g;65%), m.pt. 231°-232° C. ##STR19##
