実験手順
A slurry of [9-[(cyclopentyl)methyl]-5-carbamoylcarbazol-4-yl}oxyacetic acid, methyl ester (20 mg, 0.065 mmol) in 0.3 mL of THF and 0.1 mL of MeOH was treated with 0.1 mL of 1 N aq LiOH (0.1 mmol), and the mixture stirred at room temperature for 2 hours. The reaction was acidified with 0.2 N HCl, and the organics were removed in vacuo. The white precipitate was filtered away from the aqueous layer and rinsed with Et2O to afford 15 mg (0.0409 mmol; 63%) the title acid as a white powder. MS (ES) m/e 367 (M+1), 350 (M+H—NH3), 365 (M−1).
