Procedure
To a stirred mixture of sodium ethanethiolate (15.9 g; 0.189 mol) in 250 mL of THF and 100 mL of water at 0° C.-5° C. was added 5-nitro-2-chloropyridine (25.0 g; 0.158 mol). After 2 hours, the mixture was poured into 1200 mL of ice water, stirred for 15 minutes, and filtered. The solid was washed with water and dried in vacuo to provide 2-ethylsulfanyl-5-nitropyridine which was used without additional purification (28.1 g; 96%).
