Participants

Reaction Conditions

Reaction Steps

To a mixture of 3-chloropyridine-2-carbonitrile (C-1) (1.01 g, 7.29 mmol) and K2CO3 (1.10 g, 7.96 mmol) in DMF (10 mL) and water (1 mL) was added methyl thioglycolate (0.709 mL, 7.93 mmol) dropwise. The reaction mixture was stirred at 40° C. for 3 h. The mixture was quenched with cold water (70 mL) and placed on ice to enhance precipitation. The precipitate was collected by filtration to afford the title compound. MS (m/z): 209 (M+1)+.
