Reaction Steps
A 1M solution of BBr3 in CH2Cl2 (0.49 ml, 0.49 mmol) was added slowly to a solution of 2,2,2-trifluoro-1-[1-(4-iodophenyl)-6-methoxy-3,4-dihydro-1H-isoquinolin-2-yl]ethanone (0.150 g, 0.33 mmol) in anhydrous CH2Cl2 (10 ml) at 0° C. under N2. The reaction mixture was stirred at 0° C. for 1 hr, then warmed to rt and stirred at rt for 19 hr. MeOH (10 ml) was slowly added with stirring and the resulting solution was concentrated in vacuo to a yellow oil. Purification by flash chromatography, eluting with hexane:EtOAc (8:2) gave 0.121 g (83% yield) of yellow solid.
