Procedure
A solution of N-benzyl-2-(2,2-dimethyl-5-oxo-[1,3]-dioxolan-4-ylidene)-N-methoxy-acetamide (0.267 g, 0.917 mmol) in tetrahydrofuran (10 ml) was treated at 22° C. with 2 ml (2 mmol) of 1 M aqueous sodium hydroxide. After 1 h, the reaction mixture was acidified with 1N hydrochloric acid and extracted with ethyl acetate. The organic phase was washed with brine, dried (magnesium sulfate) and the solvent evaporated in vacuo to give 0.220 g (95% yield) of the title material as a white solid. 1HNMR 400 MHz (CDCl3) δ (ppm) : 3.70 (3H, s), 4.85 (2H, s), 6.57 (1H, s), 7.32-7.37 (5H, m).
