Reaction Steps
Dimethylamine in THF (57.9 ml, 116 mmol) was dissolved in dichloromethane (29.0 ml) and cooled to 0° C. Then, methyl (chlorosulfonyl)acetate (prepared according to: Szymonifka, M. J.; Heck, J. V. Tet. Lett. 1989, 30, 2869-72.) (10.0 g, 57.9 mmol) was added dropwise as a solution in dichloromethane (29.0 ml), while maintaining the temperature below 5° C. The resulting solution was allowed to warm to room temperature over the course of 2 h. Then, brine (200 mL) was added and the aqueous phase was extracted with dichloromethane (3×100 mL). The combined organics were dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (EtOAc/Hexanes gradient) to afford the title compound as a yellow liquid. 1H NMR (600 MHz, DMSO-D6) δ 4.25 (s, 2H); 3.68 (s, 3H); 2.78 (s, 6H). LRMS (APCI) calculated for C5H12NO4S [M+H]+, 182.0; found 182.0.
