Reaction Steps

To a solution of methyl 1-[N-(3-methylbutyl)carbamoyl]cyclopentanecarboxylate (820 mg, 3.4 mmol) in 25 mL of THF cooled to 0° C. was added dropwise a solution of lithium hydroxide monohydrate (260 mg, 6.12 mmol) in 5.0 mL of water. The reaction mixture was stirred at rt for 16 h. THF was removed under reduced pressure to give a yellow oil which was diluted with 10 mL of 1N HCl. The aqueous phase was extracted with CH2Cl2 (8×15 mL), and the extracts were combined, dried over Na2SO4, and concentrated to afford 700 mg (90%) of methyl 1-[N-(3-methylbutyl)carbamoyl]-cyclopentanecarboxylic acid as a white solid. MS [M+H]+ 228.
