Triphenylphosphine → HCID 21842622, compound

Participants

Reaction Steps

Bromine was added to a solution of triphenylphosphine (41.4 mg, 0.158 mmol) in 0.50 mL of acetonitrile until the red color persisted, and a small additional quantity of triphenylphorsphine was then added to consume the excess bromine. A solution of N-(2-(3-chlorophenyl)-5-hydroxypentyl)-N-methylbenzenesulfonamide (38.7 mg, 0.105 mmol) in 0.3 mL of acetonitrile was added. After stirring for 1 h, the reaction was quenched by a solution of sodium sulfite (20 mg) dissolved in 1.0 mL of water. The mixture was diluted with 15 mL of sodium bicarbonate and extracted with 2×20 mL of ethyl acetate. The organic layers were washed with 15 mL of brine, dried over sodium sulfate and concentrated. The crude product was purified by flash column chromatography on silica gel, eluting with of 10% ethyl acetate in hexane to give 23 mg the title compound.
