Triethylamine → N-dodecyl-2-carbobenzyloxyaminosuccinamic acid

関与物質

反応手順

N-Carbobenzyloxy-L-aspartic anhydride (1 mmol) was dissolved in 50 mL methylene chloride, followed by the addition of 1.05 eq of dodecylamine and 1.1 eq of triethylamine. The reaction was capped to prevent evaporation, and stirred for 12 hours. When no trace of starting material could be detected by thin layer chromatography (TLC) (CH2Cl2, 5% MeOH), the reaction was quenched with 20 mL 1N hydrochloric acid followed by extraction with chloroform (5×). The organic layer was dried over magnesium sulfate, and 7 was obtained as a white solid (yield 97%).
