Reaktionsschritte
Add potassium hydroxide (486.7 mmol, 32.1 g) over a solution of 2,3-dihydroxy-2-methyl-propionic acid (423.2 mmol, 50 g) in 300 mL of DMF. Stir for 1 hour at 100° C. Then add benzyl bromide (584.04 mmol, 69.46 mL) and stir overnight. Cool down the mixture and dilute with ethyl acetate. Wash organic layer with water. Wash aqueous layer with ethyl acetate several times. Combine organic layers and dry over sodium sulfate, filter and concentrate under reduced pressure. 1H NMR (CDCl3, 300 MHz): δ ppm :7.36-7.32 (m, 5H), 5.1 (s, 2H), 3.5 (s, 2H), 1.21 (s, 6H).
