Reaction Conditions:
with chlorine in chloroform at 35; for 2 h;Temperature;
Steps:
1.1 Step 1: Preparation of 5-chlorobenzodioxole
Example 1: In a reaction flask equipped with a stirrer, a reflux condenser, and a dropping funnel, 0.5000 g of benzodioxole, 10 ml of chloroform was added, and the mixture was stirred and dissolved in a dropping funnel, and 5 ml of chloroform was added. Slowly pass 1.005 g of chlorine gas, control the temperature of the reaction solution to 35 ° C, and add chlorine gas to the chloroform solution for about 5 minutes. After the completion of the addition, the reaction was stirred for 2 hours, then washed twice with water, and the organic layer was combined, washed with brine, dried over anhydrous sodium sulfate and evaporated. The yield is 96.2%.
