Lithium hydroxide, monohydrate → HCID 11235124, compound

Participants

Reaction Steps

A solution of lithium hydroxide monohydrate (0.085 g, 2.0 mmol) in water (1 mL) was added to a solution of 1-{[5-(biphenyl-4-yloxymethyl)-furan-2-carbonyl]-amino}-cyclopentanecarboxylic acid methyl ester (0.092 g 0.22 mmol) in tetrahydrofuran (3 mL) and methanol (1 mL). The mixture was stirred overnight at room temperature and then the solvents were evaporated under reduced pressure. 0.5 M NaOH was added and the solution was extracted with ether. The aqueous layer was acidified with 1 M HCl and the mixture was extracted three times with ethyl acetate. The combined organic layers were dried (sodium sulfate), filtered, and evaporated to give 1-{[5-(biphenyl-4-yloxymethyl)-furan-2-carbonyl]-amino}-cyclopentanecarboxylic acid (61 mg, 69%) as a white solid.
