1-Hydroxybenzotriazole → N-[4-[N-methyl-N-(tetrahydropyran-4-yl)aminomethyl]phenyl]-6-(4-methylphenyl)-2-methylquinoline-3-carboxamide

Participants

Reaction Steps

To a solution of 6—(4-methylphenyl)-2-methylquinoline-3-carboxylic acid (120 mg) and 1-hydroxybenzotriazole (88 mg) in DMF (5 ml) was added 1-ethyl-3—(3′-dimethylaminopropyl)carbodiimide hydrochloride (125 mg) at room temperature, and the mixture was stirred for 2 hours. To the mixture was added a solution of 4-[N-methyl-N-(tetrahydropyran-4-yl)aminomethyl]aniline (105 mg) and triethylamine (0.2 ml) in DMF (5 ml), and the mixture was stirred for 18 hours and concentrated under reduced pressure. To the residue was added water, and the mixture was extracted with chloroform. The organic layer was washed with saturated sodium chloride solution, dried with magnesium sulfate and concentrated under reduced pressure. The residue was separated and purified with column chromatography (ethanol/ethyl acetate=1:2), and recrystallized from ethyl acetate-hexane to give N-[4-[N-methyl-N-(tetrahydropyran-4-yl)aminomethyl]phenyl]-6—(4-methylphenyl)-2-methylquinoline-3-carboxamide (Compound 216) (82 mg) as pale yellow crystals.
