Procedure
To the thioester from Step 3 (2.50 g, 14.0 mmol) cooled to 0° C. is added sulfuryl chloride (1.5 mL, 18.25 mmol) over 2 min. The reaction mixture is stirred at 0° C. for 30 min then at RT for 2.5 h. The reaction mixture is concentrated and then dried on house vacuum overnight to afford 2.4 g of the desired crude product, which is used without further purification. 1H NMR (CDCl3) δ 5.83 (s, 2H), 2.19 (s, 3H);
