실험 절차

1-Chloro-4-isocyanato-2-trifluoromethyl-benzene (4.40 g, 20 mmoL) and 2-amino-3-hydroxy-2-methyl-propionic acid (2.38 g, 20 mmoL) in dioxane (100 mL) was heated at 80° C. for 6 hrs. The reaction was cooled to room temperature and concentrated HCl (2 mL) was added and the reaction mixture was heated to refluxed for 4 hrs. The solvent was removed and the residue was partitioned between ethyl acetate and water. The organic layer was washed with sat. NaHCO3, brine, dried over anhydrous Na2SO4, filtered and concentrated, then recrystallization was conducted using ethyl acetate as solvent to afford the title compound as a white solid (2.65 g, yield 41%).
