Reaction Steps

To a cold (-78° C.) solution of 2-(3-methoxybenzyl)-benzo[b]thiophene (2.10 g, 8.26 mmol) and p-anisoyl chloride (1.48 g, 8.67 mmol) in anhydrous methylene chloride (31 mL) was added tin IV chloride (2.90 mL, 24.8 mmol, 3 eq) dropwise over a period of 24 minutes. After stirring overnight in the warming dry ice bath and at ambient temperature for 7 hours the reaction mixture was poured onto water (175 mL) and the organics were extracted with diethyl ether (2×300 mL). The extracts were combined, and washed with brine. Silica gel was added and the solvent was removed. The adsorbate was flash chromatographed (97/3 petroleum ehter/ethyl acetate) to give the title compound as a white solid (1.92 g, 63%): mp 158-159° C.; MS (+FAB): [M+] 370; Anal. Calc. for C24H18O2S: C, 77.81, H, 4.90, N, 0.00. Found: C, 78.00, H, 4.76, N, 0.03.
