Triethylamine → 1-(3-tert-Butyl-1-(4-cyanophenyl)-1H-pyrazol-5-yl)-3-((5-fluoro-2-(1-(2-hydroxyethyl)-1H-indazole-5-yloxy)phenyl)methyl)urea

Participants

Reaction Steps

2,2,2-Trichloroethyl 3-tert-butyl-1-p-tolyl-1H-pyrazol-5-ylcarbamate (0.22 g, 0.529 mmol), 2-(5-(2-(aminomethyl)-4-fluorophenoxy)-1H-indazol-1-yl)ethanol (prepared as in Example 1, Steps E1-E6; 0.175 g, 0.582 mmol), and triethylamine were combined in a minimal amount of DMA and stirred at ambient temperature overnight. The reaction mixture was concentrated, and the residue was diluted with DCM. The DCM was washed with aqueous NH4Cl and aqueous Na2CO3. The organic layer was dried over MgSO4 and concentrated. The residue was purified by silica gel chromatography, eluting with 1% MeOH in ethyl acetate to provide 100 mg (32.6%) of the desired product. MS M+1 (568).
