Reaction Steps
Subsequently, 4.3 g of 2-ethylimidazo[2,1-b]-benzothiazole was added to a solution prepared from 11 g of phosphorus oxychloride and 20 ml of dimethylformamide followed by heating at 50° C. for 2.5 hours. The reaction mixture was poured onto ice water. After neutralizing with ammonium hydroxide, the precipitated crystals were filtered to give 3.88 g of 3-formyl-2-ethylimidazo[2,1-b]benzothiazole.
