Reaction Conditions:

with bromine;sodium hydroxide at 75; for 5 h;

Steps:

Sulfone bromination with sodium hypobromite-general procedure
General procedure: To a solution of NaOH (15% w/w, 8 mL) cooled to 5 °C, Br2 (0.4 mL, 15 mmol, 3 equiv) was added dropwise while maintaining the temperature of the mixture below 10 °C. Next, the sulfone (5 mmol, 1 equiv) was added in one portion. The resulting mixture was stirred for the given time (Table 1) at 75 °C. The mixture was cooled to room temperature, and the precipitate filtered off, washed with H2O, dried in air, and crystallized from 2-PrOH. See Supplementary data for the characterization of the bromination products obtained
