Aluminum chloride (2 g, 15 mmol) was suspended in 8 mL 1,2-dichloroethane and the solution was cooled to 5° C. Dimethoxymethane (0.69 mL, 7.8 mmol) over 10 min. Ethylphenylsulfide (0.88 mL, 6.5 mmol) was added and the mixture was warmed to rt. After 15 h ice water was added and the mixture was extracted with methylene chloride (3×). The combined organic fractions were dried over magnesium sulfate and concentrated. The crude material was used directly in the next step.
