Procedure
2-[(3-Pentadecylphenyl)sulfonyl]butanoic acid (84.6 g, 0.193 Mole) was suspended in ethyl acetate (700 mL) to which was added dimethylformamide (0.5 mL) and thionyl chloride (70 mL, 0.964 Mole). The mixture was heated at 70° C. for 1.5 hours, cooled, concentrated under reduced pressure, co-evaporated with ethyl acetate (2×100 mL) and the oil so obtained used as such in the next step of the reaction sequence.
