Participants

Reaction Conditions

Reaction Steps

To a suspension of 5 g (49 mmol) of sodium methane sulfite in DMF (50 mL) were added pyridine (6.3 mL) and ethyl α-bromoisobutyrate (2.9 mL). The reaction was stirred for 18 h at 50° C. under nitrogen. The reaction mixture was diluted with ethyl acetate (250 mL), washed with saturated aqueous NaHCO3 (2×100 mL), 2M aqueous HCl solution (50 mL), brine (1×50 mL) and dried over Na2SO4. Filtration, concentration under reduced pressure afforded 3.04 g of 2-methanesulfonyl-2-methyl-propionic acid ethyl ester.
