Reaction Steps
To a solution of 100 mg (0.369 mmol) of 1-(3-bromo-4-isopropoxyphenyl)acetone (from Example 228, Step C) in toluene (0.26 mL) was added bromine (0.019 mL, 0.369 mmol) dropwise via syringe. After stirring 30 min. At RT, a solution of sodium sulfite (676 mg) in water (1.5 mL)) was added and the mixture was extracted with 3×15 mL of ethyl ether. The combined organic layers were washed 20 mL of saturated sodium bicarbonate followed by 20 mL of brine. Drying over sodium sulfate and evaporation gave 119 mg of product as a red oil. Mass spectrum (NH3/CI): m/z=349 (M+1)
