Reaction Steps

A solution of 2-[10a-(4-chloro-benzenesulfonyl)-1,4-difluoro-6a,7,8,9,10,10a-hexahydro-6H-benzo[c]chromen-8-yloxy]-ethanol (1.09 g, 2.54 mmol) in CH2Cl2 (25 mL) at 0° C. was treated with Et3N (0.37 mL) and MsCl (0.65 mL), the reaction mixture was slowly warmed to room temperature. After 14 h, the reaction mixture was quenched with saturated aqueous NH4Cl and extracted with EtOAc (2×). The combined organic extracts were washed with saturated aqueous NaHCO3, dried over MgSO4 and concentrated in vacuo to afford the title compound (1.24 g, 97%): 1H NMR (CDCl3 400 MHz) δ 7.58 (d, J=8.1 Hz, 2H), 7.47 (d, J=8.1 Hz, 2H), 7.07 (m, 1H), 6.40 (m, 1H), 5.23 (dd, J=2.9, 11.7 Hz, 1H), 4.37 (dd, J=3.7, 4.4 Hz, 2H), 4.11 (d, J=11.7 Hz, 1H), 3.72 (m, 2H), 3.58 (m, 1H), 3.13 (s, 1H), 3.01 (m, 1H), 2.40 (m, 2H), 1.87 (m, 2H), 1.56 (ddd, J=1.6, 14.7, 14.7 Hz, 1H), 1.14 (m, 1H).
