A solution of 8 (3.75 g, 17.3 mmol) in 50 mL of acetonitrile was treated with p-toluenesulfonic acid monohydrate. The reaction mixture was heated to 70° C. with stirring. 4-Methoxybenzyl alcohol (2.63 g, 19.0 mmol) in acetonitrile (3 mL) was added dropwise via syringe keeping the reaction temperature at 70° C. The reaction was stirred at 70° C. for 12 h, allowed to cool to ambient temperature, and concentrated in vacuo. Chromatography afforded 9 (4.3 g, 75%) as light yellow solid.
