实验步骤: N-Ethyldiisopropylamine (3.70 ml, 21.26 mmol) was added to ethyl 4-(aminomethyl)piperidine-4-carboxylate (Intermediate 9) (3.3 g, 17.7 mmol) and 4-chloro-7H-pyrrolo[2,3-d]pyrimidine (2.72 g, 17.72 mmol) in DMA (35 ml). The resulting solution was stirred at 60° C. for 18 hours. The crude product was purified by ion exchange chromatography, using an SCX column. The desired product was eluted from the column using 7M NH3/MeOH and pure fractions were evaporated to dryness to afford ethyl 4-(aminomethyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxylate (5.08 g, 95%) as a beige solid. The crude product was purified by ion exchange chromatography The desired product was eluted from the column were evaporated to dryness

反应条件: temp:20.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Hydrogen chloride 4M in dioxane (33.2 ml, 132.7 mmol) was added to 1-tert-butyl 4-ethyl 4-(aminomethyl)piperidine-1,4-dicarboxylate (Intermediate 8) (7.6 g, 26.5 mmol) in dioxane (35 ml). The resulting solution was stirred at 20° C. for 3 hours. The crude product was purified by ion exchange chromatography, using an SCX column. The desired product was eluted from the column using 7M NH3/MeOH and pure fractions were evaporated to dryness to afford ethyl 4-(aminomethyl)piperidine-4-carboxylate (3.34 g, 67.6%) as a yellow liquid. The crude product was purified by ion exchange chromatography The desired product was eluted from the column were evaporated to dryness
