Participants

Reaction Conditions

Reaction Steps

To a stirred solution of 2-acetyl napthalene (170 mg, 1.0 mmol) and a 6-(4-fluorophenyl) imidazo[2,1-b]thiazol-5-carbaldehyde (246 mg, 1.0 mmol) in ethanol (20 ml) 10% aqueous solution of NaOH was added (5 ml). The reaction mixture was stirred at room temperature 27° C. for 4 h and the reaction was monitored by TLC using ethyl acetate-hexane (3:7) as a solvent system. The solvent was evaporated under vacuum then the residue was dissolved in ethylacetate/water. The organic layer was washed with brine and evaporated. This was further purified by column chromatography using ethyl acetate:hexane (2:8) as a solvent system to obtain the pure product (12e) as yellow solid (298 mg, 75% yield). Mp: 216-218° C.
