Reaction Steps
To a suspension of 6,7-dimethoxy-1-(4-methoxybenzyl)-1,2,3,4-tetrahydroisoquinolin-8-ol (2.26 g, 6.86 mmole) in chloroform (60 ml) was added formic trimethylacetic anhydride (1.16 g, 8.91 mmole) at 0° C. The mixture was stirred for 30 minutes and concentrated under reduced pressure. The residue was recrystallized from ethyl acetate-hexane to give intermediate 1 (2.23 g) as colorless crystals.
