Hydrochloric Acid → N-[(E,E)-4-ethyl-2,4-hexadienoyl]-L-threonine

참여 물질

반응 단계

To a solution of N-[(E,E)-4-ethyl-2,4-hexadienoyloxy]succinimide (1.19 g) in a mixture of tetrahydrofuran (50 ml) and dimethylformamide (30 ml) was added a solution of L-threonine (2.38 g) and triethylamine (2.78 ml) in water (50 ml). The mixture was stirred at ambient temperature for 6 hours and then acidified with 1N hydrochloric acid. The resulting mixture was extracted with ethyl acetate, washed with water and then dried over magnesium sulfate. The solvent was distilled off under reduced pressure to give N-[(E,E)-4-ethyl-2,4-hexadienoyl]-L-threonine (640 mg).
