PROCEDURE

实验过程

The title compound was prepared from 2-((S)-1-hydroxy-ethyl)-isonicotinonitrile (620 mg, 4.18 mmol) according to General Method C, except that 1.0 equiv. NCS and 1.0 equiv. PPh3 were used. After 24 hrs reaction time another 0.2 equiv. each of NCS and PPh3 were added and the temperature was increased to 30° C. for 12 h. Workup and purification by flash column chromatography yielded the title compound (46 mg, 7% yield) with 82% ee. 1H NMR (CDCl3) δ 8.74 (d, 1H), 7.76 (s, 1H), 7.46 (dd, 1H), 5.16 (q, 1H), 1.88 (d, 3H).
