c. 5-tert-Butyl-2-{4-[2-(4-methyl-piperazin-1-yl)-ethoxy]-phenyl}-2H-pyrazol-3-ylamine (Intermediate 13c) To a solution of Intermediate 13b (1.15 g, 5.0 mmol), 2-(4-methyl-piperazin-1-yl)-ethanol (864 mg, 6.0 mmol), and triphenylphosphine (2.62 g, 10.0 mmol) in THF (10 mL), was added diisopropyl azodicarboxylate (2.0 g, 10.0 mmol) dropwise and stirred for 75 min. The mixture was diluted with diethyl ether (50 mL) and extracted with 10percent aqueous citric acid soln (2*). The combined aqueous layers were basified with solid potassium carbonate until pH=9. The aqueous layer was then extracted with ethyl acetate (3*). The combined ethyl acetate layers were washed with brine, dried (NaSO4) and evaporated in vacuo. Purification by FCC using 0-12percent [9:1 MeOH/880 ammonia] in DCM. The resulting product was crystallised (diethyl ether) to give the title compound (270 mg, 0.756 mmol, 15percent). LCMS (Method 1): Rt 2.31, 1.72 min, m/z 358/359 [MH+].
5464-12-0, Big data shows that 5464-12-0 is playing an increasingly important role.
