Reaction Steps

To a solution of the title compound from Step 3 (2.00 g, 6.59 mmol) in DCM (200 mL) was added TEA (1 g, 9.89 mmol), NaI (898 mg, 5.99 mmol) and EtSH (613 mg, 9.89 mmol). The mixture was stirred at 30° C. for 4 hrs. The reaction was poured into water (10 mL) and extracted with EtOAc (10 mL×3). The combined organic layers were washed with brine (30 mL), dried over anhydrous Na2SO4 and filtered. Solvents were removed under reduced pressure and the residue was purified by silica gel chromatography (PE:EA=1:03:1) to give the title compound (2.1 g, 96.8%) as a white solid. 1H NMR (CDCl3, 400 MHz) δ 7.55 (d, J=2.0 Hz, 1 H), 7.24 (dd, J1=8.4 Hz, J2=2.0 Hz, 1H), 6.89 (d, J=8.4 Hz, 1H), 4.42 (q, J=8.0 Hz, 2H), 3.66 (s, 2H), 2.47-2.41 (m, 2H), 1.26-1.22 (m, 3H).
