Reaction Steps

3-nitrophenylmercaptan (5 g, 32 mmol), 3-bromopyridine (6.1 g, 38.6 mmol), ethyl 2-oxocyclohexylformate (1.1 g, 6.5 mmol), copper iodide (608 mg, 4.2 mmol), cesium carbonate (2.3 g, 70.6 mmol) were dissolved in 500 ml of DMSO, reacted under microwaves at 100° C. for 8 h. After being extracted with water and DCM, the organic phase was dried and separated with column chromatography to obtain an object product 3.2 g.
