Reaction Steps
A racemic mixture of N2-(4-(4-chloro-1H-imidazol-1-yl)-3-methoxyphenyl)-N4,N4-dimethyl-7-(4-(trifluoromethoxy)phenyl)-6,7-dihydro-5H-cyclopenta[d]pyrimidine-2,4-diamine (235 mg, 0.431 mmol from Example 100) was purified using chiral SFC to afford 29.2 mg of peak A (Example 100A) and 29.2 mg of peak B (Example 100B). 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 11 min, absorbance 268 nm, injection 5 μL of 2 mg/mL solution in methanol (multiple stacked injections), tR (peak A)=3.7 min, tR (peak B) 8.4 min. The absolute stereochemistry of individual enantiomers (Examples 100A and 100B) was not determined. LC-MS and 1H NMR analytical data for the separated enantiomers was identical to the racemate (Example 100).
