Potassium bisulfate → HCID 19752432, compound

Participants

Reaction Steps

Methyl 6-[(4-acetyl-2-ethyl-5-hydroxyphenoxy)methyl]pyridine-2-carboxylate (38 mg, 12 mmol) was dissolved in a methanol solution (2 ml), and one normal sodium hydroxide (1 ml) was added to the above solution at 0° C., and the mixture was stirred at room temperature for 1 hour. One-tenth normal potassium bisulfate was titrated to the above solution until it became pH2. Then, precipitated white crystals were separated by filtration, and washed with water, and dried to give 6-[(4-acetyl-2-ethyl-5-hydroxyphenoxy)methyl]pyridine-2-carboxylic acid.
