Methanesulfonyl chloride → HCID 86690733, compound

Participants

Reaction Steps

To a solution of 2-(2,2-dimethyl-4H-benzo[d][1,3]dioxin-5-yl)ethanol (400 mg, 1.92 mmol, 1 eq.) in THF (20 mL) were added MsCl (438 mg, 3.84 mmol, 2.0 eq.) and TEA (0.8 mL, 5.76 mmol, 3.0 eq.) at rt. The mixture was stirred at rt for 1 h and diluted with EtOAc. The organic layer was washed with water and brine, dried over Na2SO4, and concentrated to give 2-(2,2-dimethyl-4H-benzo[d][1,3]dioxin-5-yl)ethyl methanesulfonate (400 mg, crude) as a pale brown oil, which was used for next step without purification.
