实验步骤: To a solution of the compound from Step 2 1-chloroisoquinoline 2-oxide (1.2 g, 6.68 mmol) and tert-butyl (3R)-3-aminopiperidine-1-carboxylate (2.0 g, 10.02 mmol) in n-BuOH (20 mL) was added DIPEA (0.95 g, 7.35 mmol) and DMAP (81 mg, 0.668 mmol). The mixture was stirred at 120° C. for 16 h. The mixture was then poured into water (20 mL) and extracted with EtOAc (3×10 mL). The combined layers organic were dried over Na2SO4, filtered, and the filtrate was concentrated in vacuo. The crude product was purified by silica gel flash column chromatography eluting with a gradient of petroleum ether: EtOAc (1:1 to 0:1) to afford the title compound (0.8 g, 35%). extracted with EtOAc (3×10 mL) The combined layers organic were dried over Na2SO4 filtered the filtrate was concentrated in vacuo The crude product was purified by silica gel flash column chromatography eluting with a gradient of petroleum ether: EtOAc (1:1 to 0:1)
