Procedure

Diazabicycloundecene (380 mg; 2.5 mmole) was added to a solution of derivative 3,3-dimethyl-benzisoselenazoline (107 mg; 0.5 mmole) obtained above in bromoethane (1.5 ml). The mixture was stirred at room temperature for 10 h, then the same quantity of diazabicycloundecene was added again. After 14 h at room temperature, the bromoethane was evaporated off under reduced pressure. The desired product was obtained in the form of a very viscous yellow oil after purification by liquid chromatography on a silica column (eluent: cyclohexane--ethyl acetate, 6/1).
