Versuchsvorschrift

A solution of the 1St enantiomer obtained during the resolution of Compound 6 by chiral HPLC (described as the enantiomer isolated and having the retention time of 6.7 min per the conditions reported in Example 1.2) (20 mg, 0.049 mmol) in DCM (0.500 mL) was cooled to 0° C. NCS (6.60 mg, 0.049 mmol) was added and the reaction was allowed to continue at 0° C. for 15 min in a 20 mL sealed scintillation vial. After 15 min, the reaction mixture was diluted with DCM and washed with water (2×10 mL), then washed with sodium thiosulfate pentahydrate (aq) (2×10 mL), dried over MgSO4 and filtered by vacuum filtration. The filtrate was concentrated under reduced pressure to give an enantiomer of Compound 8 as a yellow solid (16.7 mg). LCMS m/z=439.8 [M+H]+; 1H NMR (400 MHz, DMSO-d6) δ ppm 1.32 (d, J=5.94 Hz, 6H), 2.25-2.34 (m, 1H), 2.52-2.58 (m, 1H), 2.77-2.87 (m, 1H), 2.94 (dd, J=16.29, 4.17 Hz, 1H), 3.63-3.73 (m, 1H), 3.96-4.04 (m, 1H), 4.12-4.19 (m, 1H), 4.76-4.83 (m, 1H), 5.07 (s, 2H), 6.86 (dd, J=8.84, 2.40 Hz, 1H), 6.96 (d, J=2.40 Hz, 1H), 7.28 (d, J=3.66 Hz, 1H), 7.30 (d, J=3.66 Hz, 1H), 7.72 (dd, J=8.72, 2.27 Hz, 1H), 7.79 (d, J=2.15 Hz, 1H), 12.32 (bs, 1H).
