The major product of the following reaction is: CH3CH(OH)CH2CH2NH2 + ethyl formate (1 equiv.) / triethylamine

1. CH3CH(OH)CH=CH2
2. CH3CH=CHCH2NH2
3. CH3CH(OH)CH2CH2NH2
4. CH3CH(OH)CH2CH2NHCHO

Correct answer: CH3CH(OH)CH2CH2NHCHO

Solution

The reaction involves the nucleophilic attack of the amine on the carbonyl carbon of ethyl formate, leading to the formation of an amide. The product retains the hydroxyl group and incorporates the formyl group from ethyl formate, resulting in the major product being CH3CH(OH)CH2CH2NHCHO.
