Reaction Steps

Add (R)-2-methylpropane-2-sulfinamide (40.5 g, 0.33 mol) portion-wise to a solution of 4-bromobenzaldehyde (65.57 g, 0.35 mol) in toluene (283 mL). Stir the mixture at ambient temperature for 15 minutes and then add sodium hydroxide (1.34 g, 0.33 mol). Stir the suspension at ambient temperature for 12 h. Add sodium sulphate (16 g) and Celite® (16 g) and stir the suspension for 15 min. Filter and concentrate the filtrate under reduced pressure. Purify the residue by silica gel chromatography eluting with hexane/EtOAc (100% to 70% hexane) to afford the title compound as a white solid (85.5 g, 88% yield). MS (m/z): 288 (M+1).
