实验步骤: A solution of cinnamyl bromide (10 g, 50.7 mmol) in 250 mL tetrahydrofuran was added dropwise to a solution of allyl amine (38 ml, 507 mmol) in 50 mL tetrahydrofuran at 0° C. the mixture was allowed to slowly come to room temperature then stirred 20 hours. The tetrahydrofuran was removed in-vacuo, and the residue was partitioned between 500 mL of ethyl acetate and 200 ml of water. The layers were separated, the organic phase was washed with water followed by brine, then dried over sodium sulfate and concentrated to an amber oil. The oil was purified by flash chromatography on an 8×15 cm silica column, eluting with 5% methanol/chloroform followed by 10% methanol/chloroform. Obtained 7.2 g of an amber oil as product. Yield=81%. NMR (300 MHz, CDCl3) δ 7.39-7.20 (m, 5H), 6.54 (d, 1H, J=16 Hz), 6.35-6.26 (m, 1H), 6.01-5.87 (m, 1H), 5.24-5.14 (m, 2H), 3.43 (d, 2H, J=7 Hz), 3.31 (d, 2H, J=6 Hz). to slowly come to room temperature The tetrahydrofuran was removed in-vacuo the residue was partitioned between 500 mL of ethyl acetate and 200 ml of water The layers were separated the organic phase was washed with water dried over sodium sulfate concentrated to an amber oil The oil was purified by flash chromatography on an 8×15 cm silica column eluting with 5% methanol/chloroform

实验步骤: 175 ml (1.27 mol) of triethylamine were added to 173 ml (1.16 mol) of cinnamyl chloride in 1,350 ml of tetrahydrofuran, the mixture was heated to 60° C., and then 105 ml (1.40 mol) of allylamine were added dropwise. The mixture was refluxed for 6 h and then stirred at room temperature for 10 h. After concentration under water pump vacuum, the contents of the flask were partitioned between methyl t-butyl ether and water (pH=10). The aqueous phase was extracted twice more with methyl t-butyl ether and subsequently the combined organic phases were extracted with a mixture of 250 ml of concentrated hydrochloric acid and 2 l of water. The aqueous phase was then extracted with 1.2 l of methylene chloride, and the methylene chloride phase washed five times with 500 ml of 10% strength hydrochloric acid each time. The combined aqueous phases were made alkaline with concentrated sodium hydroxide solution and extracted twice with methylene chloride. Drying and concentration of the organic phase resulted in 66.5 g of crude product which was distilled at 86°-88° C. under oil pump vacuum (0.25 mbar). Yield: 64 g (32%).
