N-Methylmethanesulfonamide Use and Manufacturing

Methods of Manufacturing

To a stirred solution of methylamine in EtOH (8M in EtOH, 525 mL, 4.8 eq) at 0°C, methane sulfonyl chloride (100 g, 1.0 eq) was added drop wise and stirred at rt for 16 h. After completion, the solvent was distilled off under vacuum and the residue was diluted with DCM (200 mL). The solid that separated out was filtered off and filtrate was concentrated to obtain product N-methylmethanesulfonamide as orange coloured oil (82 g, percent). 1H NMR (CDC1Example 74

Uses
