### Claisen Condensation Reaction **Objective:** Draw the major product of the Claisen condensation reaction between two molecules of this ester. Ignore inorganic byproducts. **Starting Material:** The structure of the ester is provided, featuring a carbonyl group (C=O) with an ethyl group (–CH₂CH₃) and a methoxy group (–OCH₃) attached on either side of the carbonyl carbon. **Reaction Conditions:** 1. **Reagents:** - Sodium methoxide (NaOCH₃) in methanol (CH₃OH) - Followed by an acidic workup **Diagram Explanation:** - A skeletal formula of an ester is shown with the following components: - A two-carbon chain attached to the carbonyl group. - The carbonyl carbon is bonded to an oxygen which is further bonded to a methyl group (methoxy group). - The arrow indicates that this ester undergoes a reaction under the given conditions. - The reaction conditions are outlined next to the arrow, specifying the use of a base (NaOCH₃ in CH₃OH) and an acidic workup. **Expected Outcome:** The Claisen condensation involves the base-catalyzed formation of a β-keto ester by the condensation of two ester molecules. After the removal of an α-hydrogen and subsequent nucleophilic acyl substitution, the deprotonation and acid workup will yield the final product. The ester in question will react with itself, leading to the formation of a new carbon-carbon bond. The structure of the product is not shown, and users are encouraged to visualize or draw the expected β-keto ester product formed as a result of this reaction.
