反応手順

A 500-milliliter flask was charged with 300 milliliters of concentrated sulfuric acid, chilled to 5° to 10° C. and at this temperature 17.1 grams of 3'-chloro-4'-hydroxyacetophenone was slowly added. To the stirred clear solution 20 grams of potassium nitrate was slowly added during a period of about 30-40 minutes while the temperature was maintained between 5° and 10° C. After stirring for an additional 45-60 minutes, the solution was stirred into 1,000 grams of ice. The resulting pale yellow solid was filtered and washed with water.
