Procedure

12 g Benzylamine and 25 g 4-bromo-1-buten were added to a suspension of 46 g potassium carbonate in 150 mL DMF and the mixture was heated at 50° C. for 16 h. The reaction mixture was cooled to RT, diluted with ethyl acetate, washed with water and brine, dried, concentrated, and purified by chromatographie on silica gel (hexane/ethyl acetate 50:1) to yield 18.3 g of the desired product. (M+H)+: 230
