Glycine (0.40 g, 5.25 mmol) and 0.91 mL of diisopropylethylamine (5.25 mmol) were dissolved in 4 mL DMF and 6 mL water. Dodecylisocyanate (0.72 mL, 3.0 mmol) in 7 mL tetrahydrofuran was added and the mixture was stirred for 1 h at room temperature. Water (40 mL) was added and the resulting mixture was washed with ethyl acetate twice. The aqueous layer was acidified with 6N HCl, the resulting precipitate was filtered, and then dried to provide 575 mg of the title compound.
