Participants

Reaction Steps

One hundred seventy-five grams (0.73 mol) of the ketomono acid from step 3 and 440 ml of methanol were refluxed with agitation for 3 hours with the addition of 7.3 gm of concentrated sulfuric acid. The cooled solution was neutralized with 50% sodium hydroxide solution and then methanol and water were completely removed. The residue contained, in addition to small amounts of salt (approximately 10 gm of Na2SO4), approximately 180 gm of ketomonoester (IX) (97% yield), which was further reacted in that form.
