Procedure

To a mixture of n-butanol (10 ml), water (2.5 ml) and concentrated hydrochloric acid (1 drop) were added 3,4-dihydroxyphenethylamine hydrochloride (0.63 g) and (4-methylthiophenoxy)acetaldehyde diethyl acetal (1.0 g), and the mixture was refluxed for 5 hours. After the reaction, the reaction mixture was concentrated to dryness under reduced pressure. The residue was crystallized by adding acetone, and the crystals were recrystallized by adding acetone, and the crystals were recryatallized from a mixture solvent of methanol and ether to give 1-(4-methylthiophenoxy)methyl-6,7-dihydroxy-1,2,3,4-tetrahydroisoquinoline hydrochloride (1.2 g), mp 270°C (dec.).
