実験手順

To a mixture of 1-((2S,4R)-4-amino-6-bromo-2-methyl-3,4-dihydroquinolin-1(2H)-yl)ethanone (for a preparation see Intermediate 1) (2.28 g, 8.05 mmol) and 6-chloronicotinonitrile (2.231 g, 16.10 mmol) was added NMP (20 mL) and the mixture treated with DIPEA (4.22 mL, 24.16 mmol). The mixture was split between 2 flasks and each flask was flushed with nitrogen, sealed and stirred under microwave irradiation at 200° C. for 2 h. The reaction mixtures were combined and partitioned between water and EtOAc. The aqueous layer was extracted with EtOAc (×4) and the combined organic layers were washed with water (×3), then brine and were dried (MgSO4) filtered and concentrated in vacuo. The brown solid residue was purified by chromatography (EtOAc in Hexanes gradient) to give 6-(((2S,4R)-1-acetyl-6-bromo-2-methyl-1,2,3,4-tetrahydroquinolin-4-yl)amino)nicotinonitrile (1.940 g, 5.04 mmol, 62.5% yield) as a pale yellow foam. LCMS (HpH, 2 min), Rt=1.02 min, MH+=386 (1 Br).
