Reaction Conditions

Reaction Steps

(1S)-2-(chloroacetyl)-1-cyclohexyl-1,2,3,4-tetrahydroisoquinoline (4.496 g) was dissolved in acetonitrile (100 mL). To the mixture were added potassium carbonate (6.25 g), tetra-n-butylammoniumiodide (679 mg), and 1-(aminomethyl)cyclohexanol hydrochloride (4.50 g), followed by stirring at 60° C. for 6 hours. Thereafter, the solvent was evaporated and water was added to the reaction mixture, 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 to obtain 1-[({2-[(1S)-1-cyclohexyl-3,4-dihydroisoquinolin-2(1H)-yl]-2-oxoethyl}amino)methyl]cyclohexanol (3.02 g).
