Reaction Steps
A racemic mixture of N2-(4-(4-Chloro-1H-imidazol-1-yl)-3-methoxyphenyl)-N4,N4-dimethyl-8-phenyl-7,8-dihydro-5H-pyrano[4,3-d]pyrimidine-2,4-diamine (80.1 mg, 0.130 mmol) (Example 53) was purified using chiral SFC to afford peak A (21.2 mg, 0.044 mmol) (Example 53A) and peak B (24.2 mg, 0.051 mmol) (Example 53B). SFC Method: Chiralpak OJ-H (30×250 mm, 5 μM), 35% methanol (0.1% diethylamine) in CO2, 35° C., flow rate 70 mL/min for 13 min, absorbance 268 nm, injection 5 μL of 27 mg/mL solution in methanol (multiple stacked injections), tR (peak A)=4.5 min, tR (peak B) 9.5 min. The absolute stereochemistry of individual enantiomers (Examples 53A and 53B) was not determined LC-MS and 1H NMR analytical data for the separated enantiomers was identical to the racemate (Example 53).
