3-(2-fluorophenyl)propanal

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of 964 mg (3.0 mmol) of 3-[4-(imidazo[1,2-a]pyridin-5-ylthio)butyl]thiazolidine-2,4-dione and 609 mg (4.0 mmol) of 3-(2-fluorophenyl)-1-propanal in 20 ml of ethanol, 26 mg (0.3 mmol) of piperidine was added, followed by refluxing for 4.5 hours. After the reaction mixture was cooled, the solvent was distilled off. The residue was dissolved in dichloromethane, washed with purified water and dried, after which the solvent was distilled off. The residue was purified by column chromatography (eluent, chloroform/methanol=50/1) to yield 1.11 g (81.5%, yellow oily substance) of the desired product. by refluxing for 4.5 hours After the reaction mixture was cooled the solvent was distilled off The residue was dissolved in dichloromethane washed with purified water dried after which the solvent was distilled off The residue was purified by column chromatography (eluent, chloroform/methanol=50/1)
