Reaction Conditions:

with lithium aluminium tetrahydride in diethyl ether at -5 - 5; for 3 h;Inert atmosphere;

Steps:

6 Example 6:
In a dry three-necked reaction flask and nitrogen atmosphere, add lithium tetrahydroaluminum (3.8 g, 100 mmol) and 100 mL of solvent ether.Cool down to -50°C, add ethyl 2-ethylbutyrate (IV) (14.4g, 100mmol) in ether solution dropwise with stirring, and add it in about 1 hour.Continue the reaction at 05 for 2 hours, quench the reaction with saturated aqueous ammonium chloride solution, dry with anhydrous sodium sulfate, and concentrate under reduced pressure. The residue obtained is transferred to the fractionation device, and the fraction at 145~149 is collected to obtain a colorless liquid 2-Ethyl-1-butanol (I) 9.3 g, yield 91.2%,
