Reaction Conditions

Reaction Steps

To a round-bottom flask, were added a solution of 2,4-diethyl-5-(methoxycarbonyl)benzoic acid (compound 204.5, 500 mg, 2.12 mmol, 1.00 equiv), 4-(piperidin-4-yl)benzonitrile hydrochloride (compound 1.5, 470 mg, 2.12 mmol, 1 equiv), EDC.HCl (810 mg, 4.24 mmol, 2.00 equiv), and 4-dimethylaminopyridine (520 mg, 4.24 mmol, 2 equiv) in N,N-dimethylformamide (15 mL). The reaction was stirred overnight at 25° C. Upon reaction completion, the reaction mixture was diluted with 30 mL of ethyl acetate, then washed with 1×20 mL of NH4Cl (aq.) and 1×20 mL of brine. The organic phase was dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was purified by silica gel chromatography with a solvent mixture of ethyl acetate and petroleum ether (1:1) to yield 500 mg (60%) of the title compound as a pale yellow solid.
