Procedure

A mixture of 1.32 g of ethylenediamine, 250 mg of 3-chloropyridine, and 740 mg of potassium tert-butoxide was heated at 118° C. in a sealed tube for 18 h. The reaction was cooled to room temperature, diluted with water and extracted with chloroform. The organic extracts were dried over sodium sulfate, filtered, and concentrated to give the title product as a red oil. MS (M+H)+=137.9.
