Triethylamine → Ethyl-beta-methanesulfonylamino-beta-ethoxy Acrylate

Participants

Reaction Steps

To a solution of 15.9 g of ethyl-β-amino-β-ethoxy acrylate in 60 ml of benzene was added 10.3 g of triethylamine, and a solution of 11.5 g of methanesulfonyl chloride in 40 ml of benzene was dropped thereinto with stirring. After the dropping, the resulting mixture was stirred at room temperature for 5 hours. The crystals formed were separated. The filtrate was concentrated under reduced pressure and the concentrated residue crystallized by cooling. When the crystals were washed with n-hexane and dried, 16 g of prismatic crystals of a melting point of 103° to 104° C. was obtained.
