Reaction Conditions

Reaction Steps

To a solution of 4-chloropyridine-3-carboxaldehyde (D-1) (1.4 g, 10 mmol) dissolved in DMF (10 mL) and water (1 mL) were added K2CO3 (1.66 g, 12 mmol) and methyl thioglycolate (1.07 mL, 12 mmol) portion-wise. The reaction mixture was stirred at 45° C. overnight and then quenched with cold water. The flask was placed on ice to enhance precipitation. The precipitate was collected by filtration and air-dried to afford the title compound (1.23 g). MS (m/z): 194 (M+1)+.
