Diethyl Ether → HCID 57437803, compound

Participants

Reaction Steps

To a mixture of 2.76 g (20 mmol) of 4-hydroxyphenethyl alcohol in 70 mL of anhydrous tetrahydrofuran at rt was added 4.8 g (200 mmol) of sodium hydride (95%, dry powder). After stirring at rt for 10 min, 18.5 g (80 mmol) of 2-nitrobenzenesulfonyl chloride was added. After the resulting mixture was stirred at rt for 16 h, 250 mL of ether was added. The mixture was cooled to 0° C. and water was slowly added to the the mixture to quench excess sodium hydride. After quenching process was completed, additional 300 mL of water was added. The resulting precipitate was collected via filtration, washed with water and dried in vacuo to yield 2-nitrobenzenesulfonic acid 2-[4-(2-nitrobenzenesulfonyloxy)-phenyl]-ethyl ester as a white powder (9.13 g, 90%): MS (ESI) 509 [M+H]+.
