Methanol → Methyl 2,2-dimethyl-6-[(4-phenyl-2-quinolyl)thio]-hexanoate

Participants

Reaction Steps

To a solution of 4 g of methyl 2,2-dimethyl-6-mercaptohexanoate in 100 cc of dimethylformamide, is added 0.55 g of sodium hydride (50% w/w dispersion in mineral oil). The mixture is stirred for 2 hours until effervescence has stopped. A solution of 5 g of 2-chloro-4-phenylquinoline in 50 cc of dimethyl-formamide is then added. The obtained mixture is heated to 60 C. for 8 hours. After cooling, 10 cc of methanol is added and the mixture evaporated. The resultant residue is purified by flash chromatography on silica gel (30-60 mm; eluent: 8:2 hexane/ethyl acetate) to give methyl 2,2-dimethyl-6-[(4-phenyl-2-quinolyl)thio]-hexanoate is obtained as an oil.
