실험 절차

To a mixture of 2-amino-3,4-bis(4-chlorophenyl)butane hydrochloride salt (Reference Example 1, Diastereomer a) (3.7 g, 11 mmol), 3-hydroxy-2,2-dimethylpropionic acid (2.0 g, 17 mmol) in CH2Cl2 (100 mL) was added 1-hydroxybenzotriazole (2.3 g, 17 mmol), diisopropylethylamine (7.7 mL, 44 mmol) and 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (3.2 g, 17 mmol). After stirring at room temperature overnight. The reaction mixture was diluted with EtOAc (200 mL), washed with water and saturated aqueous sodium bicarbonate, and concentrated to dryness, and the residue was purified by flash column chromatography on silica gel eluted with 50% EtOAc in hexane to give the title compound. 1H NMR (500 MHz, CD3OD): δ7.24 (d, 2H), 7.12 (d, 2H), 7.10 (d, 2H), 6.92 (d, 2H), 4.25 (m, 1H), 3.68 (ABq, 2H), 3.18 (dd, 1H), 2.93 (ddd, 1H), 2.76 (dd, 1H), 1.20 (s, 3H), 1.19 (s, 3H), 0.96 (d, 3H). LC-MS: m/e 394 (M+H)+ (3.5 min).
