Further disclosed are methods of making such polymorphic and amorphous forms.

The invention relates to methods of separating Trolox isomers (R)-Trolox and (S)-Trolox, comprising: (a) contacting a mixture of (R) and (S)-Trolox with a resolving agent selected from the group consisting of (1S,2S)-(+)-Pseudoephedrine, (R)-(+)-2-Amino-3-phenyl-1-propanol, (1R,2R)-(−)-Pseudoephedrine, and (S)-(−)-2-Amino-3-phenyl-1-propanol, wherein the resolving agent forms a solid salt with one of (R)-Trolox and (S)-Trolox, and substantially does not form a solid salt with the other; and (b) separating the solid salt from the Trolox isomer that did not form the solid salt with the resolving agent.

Disclosed are compounds of Formula (I′), methods of using the compounds as immunomodulators, and pharmaceutical compositions comprising such compounds. The compounds inhibit PD-1/PD-L1 interaction and are useful in treating, preventing or ameliorating diseases or disorders such as cancer or infections.
