Interpretation:
The way by which tolazamide is synthesized has to be shown.
Concept introduction:

Treatment of an ester with ammonia or a primary or secondary amine gives an amide.
The nucleophilic addition of the ammonia or amine to the carbonyl carbon occurs followed by a proton transfer and a tetrahedral addition intermediate is formed. The intermediate can directly alkoxide and lose a proton to the alkoxide to give products.

- write the mechanism for a decarboxylation and state the structural features necessary for a decarboxylation.arrow_forwardWhy do you wash the dichloromethane solution of your reductive amination product with sodium bicarbonate, rather than dilute aqueous HCl? a) Sodium bicarbonate is a good method of removing aldehydes from organic solvent.b) The amine product will be protonated by acid and remain in the aqueous layer as a salt.c) Sodium bicarbonate transfers the amine starting material into the aqueous layer.d) Sodium bicarbonate reacts with leftover NaBH(OAc)3 and removes it from the mixture.arrow_forwardChoose the correct phrase from the following One of the important methods for preparing cyclic amides is the reaction of Crignard reagent with cyclohexanone. The reaction of inulin with indole is given in an acidic medium that gives cyclic amide Caprolactam is a type of cyclic amide that can be prepared from cyclohexanearrow_forward
- Early organic chemists used the Hofmann elimination reaction as the last step of a process known as a Hofmann degradation—a method used to identify amines. In a Hofmann degradation, an amine is methylated with excess methyl iodide in a basic solution, treated with silver oxide to convert the quaternary ammonium iodide to a quaternary ammonium hydroxide, and then heated to allow it to undergo a Hofmann elimination. Once the alkene product is identified, working backward gives the structure of the amine. Identify the amine in each of the following cases: a. 4-Methyl-2-pentene is obtained from the Hofmann degradation of a primary amine. b. 3-Methyl-1-butene is obtained from the Hofmann degradation of a primary amine. c. 2-Methyl-1-3-butadiene is obtained from two successive Hofmann degradations of a secondary amine.arrow_forwardShow how to synthesize the following amines from the indicated starting materials below. Each of the final products may require several sequential steps. Draw the structure for each of the steps and show the reagents required.

- In the 1880's, Acetanilide, sold under the name Antifebrin, was widely used as a pain reliever and fever reducer. However, it had many adverse side effects, including cyanosis as a result of methemoglobinemia. The toxic side effects were the result of a small portion of acetanilide being hydrolyzed to aniline. Acetanilide was discontinued and replaced with phenacetin. Later studies show that both acetanilide and phenacetin are metabolized to acetaminophen. This metabolite, which we know as Tylenol, is responsible for the analgesic and antipyretic properties.
