The present invention relates to processes of preparing PD-1/PD-L1 inhibitor (R)-1-((7-cyano-2-(3'-(3-(((R)-3-hydroxypyrrolidin-1-yl)methyl)-1,7-naphthyridin-8-ylamino)-2,2′-dimethylbiphenyl-3-yl)benzo[d]oxazol-5-yl)methyl)pyrrolidine-3-carboxylic acid, or salts thereof, related synthetic intermediates, and salts of the intermediates, where the PD-1/PD-L1 inhibitor is useful in the treatment of various diseases including infectious diseases and cancer.

Process of preparing a PD-1/PD-L1 inhibitor

This application relates to solid forms and salt forms of the PD-1/PD-L1 inhibitor 4,4′-(((((2,2′-dichloro-[1,1′-biphenyl]-3,3′-diyl)bis(azanediyl))bis(carbonyl))bis(1-methyl-1,4,6,7-tetrahydro-5H-imidazo[4,5-c]pyridine-2,5-diyl))bis(ethane-2,1-diyl))bis(bicyclo[2.2.1]heptane-1-carboxylic acid), including processes of preparation thereof, where the solid forms and salt forms are useful in the treatment of various diseases including infectious diseases and cancer.

Salts and crystalline forms of a PD-1/PD-L1 inhibitor

The present invention relates to processes of preparing PD-1/PD-L1 inhibitor (R)-1-((7-cyano-2-(3'-(3-(((R)-3-hydroxypyrrolidin-1-yl)methyl)-1,7-naphthyridin-8-ylamino)-2,2&#x2032;-dimethylbiphenyl-3-yl)benzo[d]oxazol-5-yl)methyl)pyrrolidine-3-carboxylic acid, or salts thereof, related synthetic intermediates, and salts of the intermediates, where the PD-1/PD-L1 inhibitor is useful in the treatment of various diseases including infectious diseases and cancer.

The present invention relates to processes and intermediates for preparing 3-(cyanomethyl)-3-(4-{[(1R,2S)-2-phenylcyclopropyl]amino}piperidin-1-yl)azetidine-1-sulfonamide, and salts and solid forms thereof, which selectively modulate demethylase. Particular embodiments contemplate compounds and disease indications amenable to treatment by modulation of lysine specific demethylase-1 (LSD1).
