Versuchsvorschrift
To a mixture of racemic-(trans)-2-(4-aminophenyl)cyclopropanecarboxylic acid (I-1) (0.054 g, 0.305 mmol) in dichloroethane (2 mL) was added 2-[(3,4-difluorophenyl)oxy]-4-methyl-1,3-thiazole-5-carbaldehyde (0.072 g, 0.282 mmol). The mixture was stirred for 12 h followed by addition of sodium triacetoxyborohydride (0.092 g, 0.434 mmol). The mixture was stirred for 5 h at RT. Water was added (10 mL), and the layers were separated. The aqueous phase was extracted with CH2Cl2 (2×10 mL). The combined organics were dried with MgSO4 and concentrated. The crude material was purified by chromatography (EtOAc/hexanes) to give the title compound as a yellow solid (0.077 g, 51%). 1H NMR (400 MHz, DMSO-d6): δ 7.59-7.47 (m, 2H), 7.18 (m, 1H), 6.87 (d, J=8.4 Hz, 2H), 6.51 (d, J=8.4 Hz, 2H), 4.23 (s, 2H), 2.47 (m, 1H), 2.17 (s, 3H), 1.59 (m, 1H), 1.29 (m, 1H), 1.18 (m, 1H). ES-MS m/z 416.98 (MH+).
