GDC-0084 Usage And Synthesis
  • UsesGDC-0084 is an inhibitor of phosphoinositide 3-kinase (PI3K) and mTOR (1,2). Inhibitors of PI3K are useful compounds for developing treatments for brain tumors.
  • PreparationStumpf et al. at Genentech Inc. (Roche group) developed an efficient multikilogram process to synthesize the brain penetrant PI3K inhibitor, GDC‐0084, a potential drug candidate for the treatment of several brain cancers. An efficient Suzuki coupling reaction between a chloropyrimidine and an arylboronic ester using a palladium catalyst at low loading was reported. The optimized conditions were demonstrated on 6.75 kg of a chloropyrimidine intermediate, providing 7.49 kg of crude GDC‐0084 (94% yield, 99.4% HPLC purity). Using the commercially available XPhos Pd G2 catalyst, instead of the usual PdCl2(dppf)·CH2Cl2 catalyst, it was possible to reduce the catalyst loading from 2 to 0.5 mol%. A final scavenging/recrystallization combination from Si‐Thiol (a solid‐supported resin) and acetic acid/water provided the crude GDC‐0084 with the required purity and polymorphic form (off‐white solid, 6.41 kg, 83% yield, 99.7% HPLC purity).
