Reaction Steps
A racemic mixture of N-(4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenyl)-4-(3,3-difluoroazetidin-1-yl)-7-(4-(trifluoromethoxy)phenyl)-6,7-dihydro-5H-cyclopenta[d]pyrimidin-2-amine (165.2 mg, 0.279 mmol from Example 99) was purified using chiral SFC to afford 16.7 mg of peak A (Example 99A) and 17.0 mg of peak B (Example 99B). SFC Method: Chiralpak OJ-H (4.6×250 mm, 5 μM), 30% methanol (0.1% diethylamine) in CO2, 35° C., flow rate 2.0 mL/min for 20 min, absorbance 268 nm, injection 5 μL of 2 mg/mL solution in methanol (multiple stacked injections), tR (peak A)=4.9 min, tR (peak B) 15.0 min. The absolute stereochemistry of individual enantiomers (Examples 99A and 99B) was not determined LC-MS and 1H NMR analytical data for the separated enantiomers was identical to the racemate (Example 99).
