Diazomethane → HCID 178497913, compound

Participants

Reaction Steps

Excess diazomethane in ether was added portionwise over 15 mins to 9.58 g (~60 mmoles) of 2-hydroxy-6-methyl nicotinic acid in 900 mL of THF at 0°. After stirring 2 hours, excess diazomethane was removed in vacuo. The resulting white solid was filtered and washed with hexane and dried. This fluffy solid was the required methyl ester. The filtrate was concentrated. The resulting solid was redissolved in a minimum amount of THF and hexane was added until no further precipitation was observed. Solid was filtered and washed with hexane and dried to provide more of the desired compound.
