Into a 250-mL round-bottom flask containing a solution of 4-(methoxycarbonyl)-4-methylcyclohexyl 4-nitrobenzoate (4.5 g, 14.00 mmol, 1.00 equiv) in methanol/water (30 mL/6 mL) was added potassium carbonate (5.8 g, 41.97 mmol, 3.00 equiv) and the resulting solution was stirred overnight at 50° C. The reaction was quenched by the addition of NH4Cl (aq.) and extracted with 3×100 mL of ethyl acetate. The organic phase was washed with brine, dried over sodium sulfate and concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1/2) to afford the desired methyl 4-hydroxy-1-methylcyclohexane-1-carboxylate (2.2 g, 91%) as a colorless oil.
