Procedure

Part A: To a solution of 5.0 g (22 mmol) of 3-[(4-methoxyphenyl)sulfonyl]propan-1-ol from example 13 and 12.1 mL (8.8 g, 87 mmole) of triethylamine in 25 mL of methylene chloride at zero° C., was added a solution of 13.8 g (87 mmol) of sulfur trioxide-pyridine complex in 25 mL of DMSO. After 1 hour, the reaction mixture was added to 300 mL of ice, ethyl acetate was added, the organic layer was separated and washed with water, 5% potassium hydrogen sulfate solution and brine, dried with magnesium sulfate, filtered and concentrated to afford 4.1 g of 3-[(4-methoxyphenyl)sulfonyl]propan-1-al. suitable for the next reaction.
