Reaction Steps

To a mixed solution of (1R)-1-(methoxymethyl)-5-methyl-2-[(R)-(4-methylphenyl)sulfinyl]-1,2,3,4-tetrahydroisoquinoline (2.47 g) in EtOH (45 mL) and THF (10 mL) was added concentrated hydrochloric acid (3.1 mL) under stirring at 0° C., followed by further stirring for 10 minutes. To the mixture was added saturated sodium carbonate water (50 mL), followed by extraction with EtOAc. The organic layer was washed with a 1 M aqueous sodium hydroxide solution and a saturated aqueous sodium chloride solution, dried over magnesium sulfate, and then concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (chloroform:EtOH:aqueous ammonia) to obtain (1R)-1-(methoxymethyl)-5-methyl-1,2,3,4-tetrahydroisoquinoline (1.276 g).
