Procedure

To a solution of compound T1.7 (1.10 g, 3.37 mmol) and a catalytic amount of DMF (0.10 mL) in DCM (12.0 mL), was slowly added thionyl chloride (0.802 g, 6.74 mmol) at 0° C. After addition, the reaction mixture was stirred at room temperature for 1 hour. The solvent was removed under reduced pressure, and the resulting residue was purified by CombiFlash® chromatography (silica gel column eluted with hexane/EtOAc, 100/0 to 95/5) to give the title compound T1 (1.15 g). 1H NMR (400 MHz, CDCl3) δ ppm. 7.32-7.39 (m, 2H), 7.28-7.29 (m, 1H), 6.88 (t, 1H), 6.80-6.82 (m, 2H), 5.56 (s, 1H), 4.66 (s, 2H), 3.78 (s, 3H), 2.27-2.29 (m, 2H), 1.69 (t, 2H), 0.89 (s, 6H).
