Reaction Conditions

Reaction Steps

A mixture of methyl 4-bromo-2-[[(dimethylamino)carbonyl]thio]benzoate (3.2 g, 10 mmol) and 10% aqueous sodium hydroxide solution (20 g, 50 mmol) was stirred at 100° C. for 14 hrs. The reaction mixture was acidified (pH 3) by the addition of 6 N hydrochloric acid. The precipitates were collected by filtration, dissolved in ethyl acetate and dried over anhydrous magnesium sulfate. The solvent was evaporated to give the titled compound (2.3 g, 100%) as white crystals.
