Versuchsvorschrift
The title compound was prepared by a similar procedure to 8-(1-ethenesulfonyl-azetidin-3-yl)-2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene using 3,3-difluoroazetidine hydrochloride salt. 1-Ethenesulfonyl-3,3-difluoro-azetidine was isolated as a light brown oil after flash chromatography (SiO2, DCM) (171 mg, 61%). 1H NMR δ (ppm) (CDCl3): 6.56 (1H, dd, J=16.56, 9.83 Hz), 6.40 (1H, d, J=16.59 Hz), 6.20 (1H, d, J=9.83 Hz), 4.32-4.17 (4H, m)
