1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → HCID 25099275, compound

Participants

Reaction Steps

To a solution of 2-phenyl-pyrimidine-5-carboxylic acid (150 mg, 075 mmol) in DCM (10 mL) is added 1-[3-(dimethylamino)propyl-3-ethylcarbodiimide (158 mg, 0.83 mmol) and N-hydroxybenzotriazole (112 mg, 0.83 mmol) at rt and the mixture is stirred for 10 min. 1-Aminopiperidine (150 mg, 1.5 mmol) is added. The mixture is stirred at rt overnight. The mixture is washed with 2 N aqueous HCl (5 mL), saturated aqueous NaHCO3, (5 mL), and water (5 mL), dried (Na2SO4), filtered and concentrated in vacuo. The residue is purified by silica gel chromatography eluting with 10% EtOAc in heptane to afford 2-phenyl-pyrimidine-5-carboxylic acid piperidin-1-ylamide (125 mg) as a solid. MS: 290 (M+H).
