Методика

To a solution of 2-mercaptobenzophenone (2.3 g, 7.4 mmol) in diethyl ether (10 mL) was added dropwise diethyl azodicarboxylate (0.65 g, 3.7 mmol). The solution was stirred for 5 minutes at room temperature, then diluted with benzene (40 mL) and refluxed for 16 hours. The solution was cooled and concentrated in vacuo leaving a yellow liquid. The crude product was purified using silica gel chromatography (75% hexane/25% ethyl acetate) to give the title compound as a yellow foam (0.8 g, 50%);
