Acetyl chloride → (+/-)-cis-n-(4-Chloro-phenyl)-n-[1-(4-dimethylamino-benzoyl)-2-methyl-1,2,3,4-tetrahydro-quinolin-4-yl]-acetamide

Participants

Reaction Steps

To a solution of (±)-cis-1-(4-dimethylamino-benzoyl)-2-methyl-1,2,3,4-tetrahydro-4-(N-4-chlorophenyl)aminoquinoline (120 mg, 0.29 mmol) in methylene chloride (2 mL) was added diisopropylethylamine (37 mg, 0.051 mL, 0.29 mmol) followed by acetyl chloride (2 mL). The mixture was stirred at rt 4 h. The mixture was concentrated under reduced pressure, dissolved in ethyl acetate, washed with sat. aqueous sodium bicarbonate, brine and dried over sodium sulfate. The drying agent was removed by filtration under reduced pressure, concentrated and purified by silica gel chromatography (100% hexanes-25/75 hexanes/ethyl acetate gradient) to afford pure (±)-cis-N-(4-chloro-phenyl)-N-[1-(4-dimethylamino-benzoyl)-2-methyl-1,2,3,4-tetrahydro-quinolin-4-yl]-acetamide (45 mg, 34%).
