Reaction Steps

To a stirred solution of 5-amino-2,2-difluorobenzo-1,3-dioxole (2.8 g, 16.17 mmmol) in 25 mL of anhydrous toluene was dropwise added propargyl bromide (0.99 mL, 11 mmol). The mixture was heated to 80° C. overnight after which it was allowed to cool to ambient temperature and filtered. The filtrate was concentrated under reduced pressure and purified by column chromatography using DCM as eluant to provide the titled compound. 1H NMR (CDCl3) δ ppm 2.22 (1H), 3.85 (2H), 6.30-6.85 (3H); MS (ESI) 212 (M+H).
