In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 35100-92-6 as follows. 35100-92-6
4 – ((2,5-dichloro-4-yl) amino) -3-ethyl piperidine-1-carboxylate (0.27g, 0.71mmol) in anhydrous 1,4-dioxane was suspended inSix rings (6.0mL), to which was added 1,5-dimethyl -1H- pyrazol-3-amine (0.16g, 1.44mmol), palladium acetate (32mg, 0.14mmol), BINAP (90mg, 0.14mmol) and cesium carbonate (0.47g, 1.43mmol). The reaction mixture was placed in a sealed tube, exhausted systemAir, refilled with nitrogen repeatedly, and then the reaction was heated to 150 deg.] C, reacted for 2 hours under microwave irradiation. The reaction mixture was reducedPressure concentrated. The resulting residue was purified by silica gel column chromatography (DCM / 3M solution of NH3 in MeOH (v / v) = 100/1 to 50/1 to 30/1 to 10/1)Purified to give 4 – ((5-chloro-2 – ((1,5-dimethyl–1H- pyrazol-3-yl) amino) pyrimidin-4-yl) amino) -3-ethylpiperidine – 1- carboxylate as a yellow solidBody (0.19g, 60% yield) and 4 – ((2 – ((1,5-dimethyl–1H- pyrazol-3-yl) amino) pyrimidin-4-yl) amino) -3-ethyl piperidine-1-carboxylic acid tert-butylEster as a brown solid (0.20g, crude yield 67%, non-pure).
