Benzyl Bromide → HCID 563866, compound

Participants

Reaction Steps

Part A: To a solution of 10.04 g (43 mmol) of N-(2-hydroxyethyl)-4-methoxybenzenesulfonamide from Example 1 in 85 mL of anhydrous DMF, was added 17.8 g (128 mmol) of powdered potassium carbonate and then 8.2 g (48 mmol) of benzyl bromide. After 24 hours, ethyl acetate and water was added, the organic layer separated and washed 3×s with brine, dried with sodium sulfate, filtered and stripped to afford 14.3 g of crude product. This was recrystallized from tert-butylmethyl ether/hexane to afford 9.0 g of the desired N-(hydroxyethyl)-N-(phenylmethyl)-4-methoxybenzenesulfonamide.
