LAB 12: SYNTHESIS OF LIDOCAINE Experimental Procedure Step 2: Preparation of Lidocaine, 2-(Diethylamino)-N-(2,6-dimethylphenyl)acetamide – Step 1- Preparation of N-(2,6-Dimethylphenyl)chloroacetamide 1. To a pre-weighed 50-ml round bottomed flask, add the pressed-dry amide 1 and re-weigh the flask to get an exact amount of amide 1. 1. measure out 3.0 mL of 2,6- dimethylaniline into a 10-mL graduated cylinder and set aside in your hood. 2. sequentially add 7.5 mL diethylamine, 25 mL toluene and a few boiling stones. Attach a water-cooled reflux condenser to the round bottomed flask. 2. measure out 15-ml of glacial acetic acid and add it to a 125 mL Erlenmeyer flask. 3. Reflux the reaction mixture for 60 min. 3. Add the amine (2,6- dimethylaniline), via a Pasteur pipet, to the acetic acid in the Erlenmeyer flask. 4. Cool to room temperature, Transfer to a separatory funnel and wash the organic layer with 3x50 mL portions of 4. Transfer 2 mL of 2-chloroacetyl chloride to the Erlenmeyer…
