Reaction Steps

Diethylaminosulphur trifluoride (76 mg) was added to an methylene chloride (20 mL) solution of 3-(5-fluoro-4-hydroxy-3,3-dimethyl-3,4-dihydroisoquinolin-1-yl)quinoline (50 mg, 0.16 mmol), followed by stirring for 1 hour under ice cooling, pouring water, extracting with ethyl acetate, and applying the resulting residue to chromatography to obtain 45 mg (yield 90%) of the target compound.
