Tyramine → HCID 9850644, compound

Participants

Reaction Steps

To a mixture of (±)-3-{[2-(4,5-diphenyloxazol-2-yl)-2-cyclohexen-1-yl]methyl}benzoic acid (300 mg, 0.690 mmol) and tyramine (123 mg, 0.897 mmol) in DMF (5 ml) was added 1-hydroxybenzotriazole (140 mg, 1.04 mmol) and 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrochloride (265 mg, 1.38mmol). After stirring the resulting mixture at room temperature for 3 hours, the reaction mixture was diluted with EtOAc (30 ml), washed with 1N-hydrochloric acid, water, saturated sodium hydrogencarbonate solution, water and brine successively, dried over magnesium sulfate, and evaporated in vacuo. The residue was purified by silica gel column chromatography (hexane:EtOAc, 3:2 elution) to give (±)-N-[2-(4-hydroxyphenyl)ethyl]-3-{[2-(4,5-diphenyloxazol-2-yl)-2-cyclohexen-1-yl]methyl}benzamide (358.4 mg, 94%).
