Reaction Steps

To a solution of 4-bromo-pyridine-3-carbaldehyde (1.50 g, 8.06 mmol) in DMF (10 mL) and water (1 mL) was added K2CO3 (1.34 g, 9.68 mmol) and methyl thioglycolate (0.87 mL, 9.68 mmol). The mixture was heated at 45° C. for 18 hours. The reaction mixture was removed from the heating bath and diluted with water (50 mL). After 1 hour, the fluffy solid that formed was filtered and washed with water. The material thus obtained was dried in a 60° C. vacuum oven to a constant weight of 0.92 g (59%). MS m/z 194 (M+H)+.
