Reaction Steps
A racemic mixture of N2-(4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenyl)-N4-methyl-7-(4-(trifluoromethoxy)phenyl)-6,7-dihydro-5H-cyclopenta[d]pyrimidine-2,4-diamine (86 mg, 0.162 mmol from Example 97) was purified using chiral SFC to afford 36.6 mg of peak A (Example 97A) and 31.5 mg of peak B (Example 97B). 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 12 min, absorbance 268 nm, injection 5 μL of 2 mg/mL solution in methanol (multiple stacked injections), tR (peak A)=3.4 min, tR (peak B) 7.5 min. The absolute stereochemistry of individual enantiomers (Examples 97A and 97B) was not determined LC-MS and 1H NMR analytical data for the separated enantiomers was identical to the racemate (Example 97).
