Reaction Steps

A mixture of 3-acetyl-4-hydroxy-benzenesulfonic acid (3.0 g) (prepared according to T. Pfliegel et. al., Acta Chim. Acad. Sci. Hung., 98(2) 231-240(1978)) in tetramethylenesulfone (6 mL) and acetonitrile (6 mL) under argon was treated with triethylamine (1.94 mL) and N,N-dimethylacetamide (0.32 mL). This was stirred for 30 min and POCl3 was added dropwise maintaining the temperature below. 25° C. The reaction was stirred for 24 hr, cooled to 10° C. and quenched with water (15 mL). This mixture was warmed to 60° C. and stirred for 1 hr, at which point a precipitate formed which was then filtered and dried to give 2.34 g (72%) of 3-acetyl-4-hydroxybenzenesulfonylchloride.
