Procedure

Sodium methanethiolate (44.6 mg) was added to a solution of methyl 5-chloropyrazine-2-carboxylate (87 mg) in hexamethylphosphorous triamide (1 mL) at room temperature, followed by stirring for 13 hours and 30 minutes. Water was added to the reaction solution, followed by extraction with ethyl acetate. The organic layer was concentrated under reduced pressure. The residue was purified by NH-silica gel column chromatography to obtain the title compound (6.8 mg).
