Procedure

tert-butyl rel-{(3S,4S)-3-[(5-bromo-6-cyanopyridin-3-yl)amino]-1,1-dioxidotetrahydro-2H-thiopyran-4-yl}carbamate (890 mg, 2.00 mmol) was separated into its respective enantiomers by SFC column chromatography (20% ethanol in CO2 on chiral IC-H 2.1×25 cm column, 5 uM particle size) to afford tert-butyl rel-{(3S,4S)-3-[(5-bromo-6-cyanopyridin-3-yl)amino]-1,1-dioxidotetrahydro-2H-thiopyran-4-yl}carbamate (Enantiomer 1, elution time 8.31 minutes) and tert-butyl rel-{(3R,4R)-3-[(5-bromo-6-cyanopyridin-3-yl)amino]-1,1-dioxidotetrahydro-2H-thiopyran-4-yl}carbamate (Enantiomer 2, elution time 9.93 minutes).
