Reaction Steps
To a solution 3-aminopyridine (3.00 g, 27.0 mmol) in methylene chloride (110 mL) at 23 ° C. was added triethylamine (7.53 mL, 54.0 mmol) and N,N-dimethylarninopyridine (330 mg, 2.70 mmol). The solution was cooled to 0° C. and chloroethyloxalate 4.42 g, 32.4 mmol) was added in a dropwise fashion. The reaction mixture was stirred at 0° C. for 2 hours and then quenched with water (30 mL) and partitioned. The organic portion was washed with 10% sodium bicarbonate solution (30 mL), dried over anhydrous sodium sulfate and concentrated under reduced pressure to provide 4.30 g of the title compound.
