실험 절차

To a slurry of (R)-7-chloro-2,2-bis(fluoromethyl)chroman-4-aminium (2S,3S)-3-carboxy-2,3-dihydroxypropanoate (0.20 g, 0.51 mmol) in CH2Cl2 (1.3 mL) was added the product of Example 252A (0.10 g, 0.51 mmol) and diisopropylethyl amine (0.088 mL, 0.51 mmol). The mixture was stirred at ambient temperature overnight then placed directly onto a silica gel column. Elution with a 20-60% EtOAc/hexane gradient afforded the title compound (0.18 g, 76% yield). 1H NMR (300 MHz, DMSO-d6) δ ppm 10.12 (s, 1H), 9.63 (s, 1H), 7.98 (d, J=8.1 Hz, 1H), 7.28 (d, J=8.3 Hz, 1H), 7.11 (d, J=8.1 Hz, 1H), 7.03 (dd, J=8.3, 2.1 Hz, 1H), 6.99-6.92 (m, 2H), 6.90 (d, J=1.9 Hz, 1H), 5.84-5.73 (m, 1H), 4.77-4.62 (m, 2H), 4.58-4.50 (m, 2H), 2.83 (dd, J=8.4, 6.6 Hz, 2H), 2.43 (dd, J=8.4, 6.7 Hz, 2H), 2.34 (dd, J=13.5, 5.8 Hz, 1H), 2.12-2.00 (m, 1H); MS (ESI) m/z: 451.9 (M+H)+.
