Participants

Reaction Steps

A solution of 6-methyl-1,2-pyridine dicarboxylic acid (25 g, 138 mmol) and acetic acid (42 mL, 733 mmol) in DME (150 mL) is treated with pyridine (22 mL, 272 mmol) and stirred at room temperature for 2 h. The pale yellow solution is diluted with ether (250 mL) and then hexane (1250 mL) is added slowly. A white precipitate is formed. The solution is cooled to 0° C. for 30 min and the white solid is collected by filtration. The solid is washed with hexane and dried to give the title compound as a white solid (16.7 g, 74%).
