Participants

Reaction Steps

2-[(4R,6S)-6-hydroxymethyl-2,2-dimethyl-[1,3]dioxan-4-yl]-N-methoxy-N-methyl-acetamide (10.0 g), dichloromethane (150.0 mL), and triethylamine (17.0 mL) were added to a reactor. Methanesulfonyl chloride (4.7 mL) was added to the reaction mixture, which was then stirred for 2 hours. Water (200.0 mL) was added to the reaction mixture under stirring. The separated organic layer was washed with 0.5N hydrochloric acid solution (100.0 mL) and then concentrated under reduced pressure to obtain 2-[(4R,6S)-6-methanesulfonyloxymethyl-2,2-dimethyl-[1,3]dioxan-4-yl]-N-methoxy-N-methyl-acetamide (13 g).
