Reaction Steps
A flask was charged with 2-chloro-4-nitropyridine (12.75 g, 80.4 mmol), (4-methoxyphenyl)methanethiol (12.40 g, 80.4 mmol) and DMF (100 mL). Cesium carbonate (31.43 g, 96.48 mmol) was added in portions, and the mixture was stirred for 2 hours at ambient temperature. The solution was diluted with dichloromethane (250 mL) and washed with diluted sodium bicarbonate solution, dried over magnesium sulfate, filtered and evaporated. The resulting yellowish residue was triturated with hexanes and the solid was filtered to obtain the desired product (18.1 g, 85%) as a pale yellow powder.
