Yield: 86%
Reaction Conditions:
in methanol;toluene at 0 - 30; for 3 h;Green chemistry;
Steps:
1.3-3.3
3,9.31 g (0.15 mol) of formylhydrazine was dissolved in 150 ml of methanol, and after cooling to 0 ° C, 150 ml of a toluene solution in which 29.56 g (0.18 mol) of (S)-2-benzyloxypropanal was dissolved was added.After slowly raising the temperature to 25-30 ° C, the reaction was stirred at this temperature for 3 hours;After completion of the reaction, the solvent was removed by rotary evaporation, and 80 ml of ethyl acetate was added to the residue, and the mixture was stirred at 25-30 ° C for 2 hours, and the precipitate was filtered off. After the mother liquid was removed from ethyl acetate, 80 ml of petroleum ether was added to the mixture, 25-30 ° C After stirring for 2 hours, the precipitate was filtered off and dried to give the product (S)-N'-(2-benzyloxypropylidene)formylhydrazide.31.90 g (0.155 mol), yield 86%.
