Reaction Steps
EDC.HCl (1.5 eq), HOBt (2 eq) and 2-methyl-5-(1-piperazinyl)quinoline (D3)(1 eq) were added sequentially to a stirred solution of [3-(1H-pyrazol-1-yl)phenyl]acetic acid (D19)(1.1 eq) in dimethylformamide at room temperature under an inert atmosphere. The solvent was removed by means of an SCX cartridge. The crude material was purified on SPE cartridge (Silica) eluting with a gradient from dichloromethane/MeOH 99/1 to dichloromethane/MeOH 98/2 affording the title compound in 74% yield.
