Sodium Hydroxide → HCID 11482191, compound

Participants

Reaction Steps

To a solution of [(5-chloro-1H-pyrrolo[2,3-c]pyridine-2-carbonyl)amino] acetic acid ethyl ester (EXAMPLE 39, 500 mg, 1.8 mmol) in THF (30 mL) was added sodium hydroxide solution (1.8 mL, 2M, 3.6 mmol) and the reaction stirred at rt for 4 h. The solvent was removed in vacuo and the solid partitioned between hydrochloric acid (1M, 100 mL) and ethyl acetate (2×100 mL). The aqueous layer was concentrated in vacuo and the solid residue suspended in water (10 mL), filtered and dried to give the title compound as an off-white solid. δH (d6 DMSO): 3.97 (2H, d), 7.18 (1H, s), 7.76 (1H, s), 8.57 (1H, s), 9.17 (1H, t), 12.32 (1H, s); m/z (ES+)=254 [M+H]+.
