実験手順

Ethyl 4-((2S,4R)-1-acetyl-4-amino-2-methyl-1,2,3,4-tetrahydroquinolin-6-yl)benzoate (for a preparation, see Intermediate 16) (300 mg, 0.851 mmol) and 6-chloronicotinonitrile (236 mg, 1.702 mmol) in anhydrous NMP (5 mL) were treated with DIPEA (0.445 mL, 2.55 mmol). The reaction vial was sealed and heated under microwave irradiation to 200° C. for 2 h. The cooled solution was diluted with water to −20 mL, stirred and the resulting sticky solid isolated by decantation. The solid was dissolved in EtOAc, the solution washed with brine and dried by passing through a hydrophobic frit. The solution was concentrated in vacuo and the residue purified by MDAP (Formate) to give crude ethyl 4-((2S,4R)-1-acetyl-4-((5-cyanopyridin-2-yl)amino)-2-methyl-1,2,3,4-tetrahydroquinolin-6-yl)benzoate (120 mg) as a beige gum which was used directly in the next step without further purification. LCMS: (Formate, 2 min), Rt=1.12 min, MH+455.
