1,1'-(9,9-Dimethyl-9H-xanthene-4,5-diyl)bis(1,1-diphenylphosphine) → tert-butyl (1S,2R)-2-(4-cyano-3-(1-methyl-1H-pyrazol-4-ylamino)phenylamino)cyclohexylcarbamate

Participants

Reaction Steps

A mixture of tert-butyl (1S,2R)-2-(3-bromo-4-cyanophenylamino)cyclohexylcarbamate (150 mg, 0.380 mmol), 1-methyl-1H-pyrazol-4-amine dihydrochloride (80 mg, 0.470 mmol), sodium phenoxide trihydrate (300 mg, 1.76 mmol), xantphos (30 mg, 0.051 mmol) and Pd2(dba)3 (30 mg, 0.032 mmol) in dioxane (3 mL) was degassed with Ar, then was heated at 170 C for 30 min by microwave. It was concentrated in vacuo. The residue was purified by HPLC to give tert-butyl (1S,2R)-2-(4-cyano-3-(1-methyl-1H-pyrazol-4-ylamino)phenylamino)cyclohexylcarbamate (50 mg).
