Reaction Steps
A 250-mL round-bottom flask, purged and maintained with an inert atmosphere of nitrogen, was charged with 4-hydroxycyclohexane-1-carboxylic acid (15.7 g, 108.90 mmol, 1.00 equiv) in methanol (90 mL). Sulfuric acid (0.8 mL) was added to the mixture slowly. The resulting solution was stirred for 10 hr at 60° C. The reaction was then quenched by the addition of 200 mL of sodium bicarbonate (sat.). The resulting solution was extracted with 3×200 mL of ethyl acetate and the organic layers combined and dried over anhydrous sodium sulfate and concentrated under reduced pressure. The resulting trans-methyl 4-hydroxycyclohexane-1-carboxylate (16.6 g, 96%) was obtained as a light yellow oil.
