A racemic mixture of N2-(4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenyl)-7-(4-chlorophenyl)-N4-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidine-2,4-diamine (37 mg, 0.077 mmol from Example 94) was purified using chiral SFC to afford 10.5 mg of peak A (Example 94A) and 13.6 mg of peak B (Example 94B). SFC Method: Chiralpak OJ-H (4.6×250 mm, 5 μM), 35% 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 50:50 methanol/chloroform (multiple stacked injections), tR (peak A)=5.3 min, tR (peak B) 14.9 min. The absolute stereochemistry of individual enantiomers (Examples 94A and 94B) was not determined LC-MS and 1H NMR analytical data for the separated enantiomers was identical to the racemate (Example 94).
