How is tert-butyl 4-[4-[6-amino-5-[(1R)-1-(2,6-dichloro-3-fluoro-phenyl)ethoxy]-3-pyridyl]pyrazol-1-yl]piperidine-1-carboxylate (CAS: 877399-51-4) typically synthesized?

This compound is typically synthesized via a multi-step process involving the formation of an ethoxy derivative of a pyridine ring, followed by its coupling with a pyrazole moiety, and finally, an amino substitution. The reaction yields a high purity product with good selectivity, and the overall yield is around 70-75%. Commonly used catalysts include organometallic reagents and phase transfer catalysts.
