Procedure

A solution of methanesulfonic acid 2-[10a-(4-chloro-benzene sulfonyl)-1,4-difluoro-6a,7,8,9,10,10a-hexahydro-6H-benzo[c]chromen-8-yloxy]-ethyl ester (180 mg, 0.355 mmol) in DMF (5 mL) was treated with NaN3 (46 mg, 0.707 mmol) and the reaction mixture was heated to 80° C. After 16 h, the reaction mixture was cooled to ambient temperature and diluted with saturated aqueous NH4Cl and extracted with EtOAc (2×). The combined organic extracts were washed with H2O, saturated aqueous NaHCO3, brine, dried over MgSO4, and concentrated in vacuo to afford the title compound (153 mg, 95%): 1H NMR (CDCl3 400 MHz) δ 7.63 (d, J=8.1 Hz, 2H), 7.49 (d, J=7.3 Hz, 2H), 7.07 (m, 1H), 6.42 (m, 1H), 5.25 (dd, J=2.9, 11.7 Hz, 1H), 4.12 (d, J=11.7 Hz), 3.60 (m, 2H), 3.36 (m, 2H), 3.02 (m, 1H), 2.37 (m, 2H), 1.94 (m, 2H), 1.56 (m, 2H), 1.16 (m, 2H).
