Borane;tetrahydrofuran → HCID 18787383, compound

Participants

Reaction Steps

Borane THF complex (56 ml of 1M in THF, 56 mmol) was slowly added to a solution of 4-[2-ethoxycarbonyl-6-hydroxyphenyl]butanoic acid in THF at 0° C. The solution was stirred for 2 hr and allowed to warm to room temperature. The reaction was quenched slowly with aqueous acetic acid (5 ml of 50%) and stirred until the bubbling subsided. The mixture was concentrated in vacuo to a slurry, which was dissolved in cold 10% potassium carbonate. The solution was extracted with ethyl acetate twice. The organic extracts were dried with brine and concentrated in vacuo to a tan oil that solidified upon standing (5.14 g, 84.9%).
