実験手順
((2R*,3R*,4S*)-4-Amino-4-(2,4-difluorophenyl)-2-methyltetrahydrofuran-3-yl)methanol (120 mg, 0.49 mmol) was dissolved in DCM (2 mL). Benzoyl isothiocyanate (66 μl, 0.49 mmol) was added and the reaction was stirred at room temperature for 30 minutes. The reaction mixture was concentrated in vacuo and purified by column chromatography, eluting with 0-30% EtOAc in n-hexane to leave the title compound as a yellow oil (165 mg). 1H NMR (400 MHz, CDCl3) δ ppm: 11.81 (s, 1H), 8.89 (s, 1H), 7.84-7.91 (m, 2H), 7.62-7.75 (m, 2H), 7.49-7.58 (m, 2H), 6.91 (dt, J=1.71, 8.38 Hz, 1H), 6.80 (ddd, J=2.63, 8.80, 11.80 Hz, 1H), 4.69 (d, J=10.15 Hz, 1H), 4.39 (dd, J=1.71, 10.15 Hz, 1H), 3.91-4.08 (m, 3H), 2.85 (dd, J=4.58, 6.79 Hz, 1H), 2.59 (dt, J=3.73, 8.10 Hz, 1H), 1.37 (d, J=5.99 Hz, 3H).
