Versuchsvorschrift

To a solution of (S)-3,3,3-trifluoro-2-hydroxy-2-methylpropionic acid (3.0 g, 17.4 mmol) in 60 ml of ether was added a solution of diazomethane in ether until a yellow coloration remained. The reaction mixture was then stirred 30 min at room temperature and concentrated to dryness to afford the title compound. 1H NMR (400 MHz, acetone-d6): δ 5.67 (s, 1H), 3.85 (s, 3H), 1.57 (s, 3H).
