Reaction Conditions

Reaction Steps

Suspend 6-methyl-pyridine-2-carboxylic acid (10 g, 72.9 mmol) in methylene chloride (200 mL). Cool to 0° C. Add methanol (10 mL), 4-dimethylaminopyridine (11.6 g, 94.8 mmol), and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC) (18.2 g, 94.8 mmol). Stir the mixture at room temperature for 6 hours, wash with water and brine, and dry over sodium sulfate. Filter the mixture and concentrate in vacuo. Chromatograph the residue on SiO2 (50% ethyl acetate/hexanes) to obtain the desired subtitled intermediate, 9.66 g (92%), as a colorless liquid.
