Reaction Steps

Methyl 6-[(3-benzyloxy-5-isopropoxybenzoyl)amino]-3-pyridinecarboxylate (1.92 g, 4.57 mM) was dissolved in THF (100 ml) and then ethanol (100 ml) and 10% palladium on carbon (250 mg) were added. The reaction was stirred at ambient temperature under an atmosphere of hydrogen (balloon) for 20 hours and was then filtered through diatomaceous earth. The filtrates were concentrated under reduced pressure to give methyl 6-[(3-hydroxy-5-isopropoxybenzoyl)amino]-3-pyridinecarboxylate as a colourless solid (1.42 g); H1 NMR δ (d6-DMSO) 1.24 (6H d) 3.85 (3H s) 4.62 (1H sept) 6.49 (1H s) 6.97 (1H s) 7.04 (1H s) 8.30 (2H s) 8.89 (1H s) 9.67 (1H s) 11.01 (1H s br); [M+H]-331; [M−H] 329.
