Participants

Reaction Conditions

Reaction Steps

4 g(50 mmol) of L-alanine and 2 g(50 mmol) of NaOH were added to 30 ml of distilled water. The mixture was cooled to 0° C. and then stirred vigorously. To the mixture was added slowly a solution of 7.1 g(50 mmol) of morpholinecarbonyl-chloride in 30 ml of tetrahydrofuran, while adjusting the whole mixture to pH 8.5-pH 9.5 with the addition of 0.05N NaOH. After the reaction was completed, the reaction mixture was acidified to pH 2 with 6N HCl. The reaction mixture was extracted with a mixed solvent of ethyl acetate and THF(1:1) (30 ml×3) and the organic layer was concentrated under a reduced pressure to give 4 g of the title compound(yield: 40%).
