Tetrahydrofuran → HCID 58046540, compound

Participants

Reaction Steps

This step was achieved using a Zymark XP2 synthetic chemistry robot. A solution of 5-methyl-1′-[trans-3-(4-chlorophenyl)allyl]spiro[indoline-3,4′-piperidine] (2 ml of a solution derived from dissolving 1.43 g in 100 ml of THF) was added to a robot tube and the solvent was removed in vacuo. 4-Cyanobenzoic acid (28 mg) was weighed into a different robot tube. A solution of 2-chloro-1,3-dimethyl-2-imidazolinium hexafluorophosphate (2 ml of a solution derived from dissolving 4.80 g in 180 ml of chloroform) and a solution of triethylamine (2 ml of a solution derived from dissolving 8.68 ml in 250 ml of chloroform) were added to the acid and the tube was agitated and allowed to stand for 30 minutes. A 2 ml aliquot of the acid solution was added to the tube containing the dry amine. This tube was agitated and allowed to stand overnight. The reaction mixture was washed with 1M aqueous sodium carbonate solution and the solvents were evaporated. The crude mixture was purified by MS directed liquid chromatography to give the desired amide, 2.9 mg. MS (ES+) 482/484 (M+H+).
