PROCEDURE

实验过程

Glycine (7.5 g, 0.1 moles) is dissolved in 30 ml of aqueous sodium hydroxide solution (8 g, 0.2 moles) and cooled in ice and methacryloyl chloride (10.45 g, 0.1 moles), dissolved in 10 ml of chloroform, is added dropwise with stirring. After that, the reaction is allowed to continue for one hour at room temperature. The solution, cooled in ice, is acidified to a pH of 2 with 5N aqueous hydrochloric acid and exhaustively extracted with ethyl acetate. The organic solution is dried over sodium sulfate and evaporated under vacuum, 10 g (70%) of a crystalline product of N-methyacryloyl glycine with a melting point of 104° C. to 105° C. being obtained.
