실험 절차

A mixture of N-(2-chloro-5-fluoropyrimidin-4-yl)-octahydro-5,5-dimethylindolizin-7-amine (racemic, single diastereomer; 200 mg, 0.669 mmol, 1 equiv), 2-((R)-tetrahydrofuran-3-yloxy)-5-aminobenzonitrile (191 mg, 0.937 mmol, 1.4 equiv), and PTSA monohydrate (127 mg, 0.669 mmol, 1 equiv) in IPA (7 ml) were heated to 70° C. for 3 days. After cooling to ambient temperature, the crude mixture was concentrated to dryness and taken in water, EtOAc, and 1N NaOH. The layers were separated. The organic layer was washed with 1N NaOH (×2), dried over Na2SO4, filtered, and concentrated to dryness. The crude product was purified by flash chromatography and eluted with DCM:2M NH3/MeOH=100:0 to 96:4 using 1% 2M NH3/MeOH increments to give compound 2-((R)-tetrahydrofuran-3-yloxy)-5-(5-fluoro-4-(octahydro-5,5-dimethylindolizin-7-ylamino)pyrimidin-2-ylamino)benzonitrile (Compound 57) (two diastereomers; 295 mg, 95%) as a solid.
