Procedure
2-{[2-(1-cyclohexyl-3,4-dihydroisoquinolin-2(1H)-yl)-2-oxoethyl]amino}ethanol (342 mg) was dissolved in EtOH (5 mL). 1-oxaspiro[2.5]octane (363 mg) and water (5 mL) were added thereto, followed by stirring under heating at reflux for 2 days. The solvent was evaporated and water was added to the reaction liquid, followed by extraction with chloroform. The extract was washed with saturated brine, and then dried over magnesium sulfate. The solvent was evaporated and the resulting residue was purified by silica gel column chromatography (chloroform-MeOH) to obtain 1-({[2-(1-cyclohexyl-3,4-dihydroisoquinolin-2(1H)-yl)-2-oxoethyl](2-hydroxyethyl)amino}methyl)cyclohexanol (346 mg).
