(2S)-1-Azido-4,4,4-trifluoro-2-butanol → HCID 34178040, 화합물

The slurry of (S)-1-azido-4,4,4-trifluorobutan-2-ol (2.26 g, 13 mmol) and Pd/C (200 mg) in MeOH (20 mL) was subjected to balloon hydrogenation for 18 hr. The reaction mixture was filtered through a celite pad and the filtrate was concentrated in vacuo to give (S)-1-amino-4,4,4-trifluorobutan-2-ol as a crude product (1.02 g, 45%). NMR: 400 MHz 1H (CDCl3) 3.88 ppm, 1 H, m, J=7.85, 7.85, 3.84, 3.74 Hz; 2.93 ppm, 1 H, dd, J=12.74, 3.52 Hz; 2.61 ppm, 1H, dd, J=12.52, 8.13 Hz; 2.34 ppm, 1 H, m; 2.21 ppm, 1 H, m; 1.91 ppm, 3 H, s.
