Phosphorus oxychloride → 2-{2-{[2-(4-Tert-butylthiazol-2-yl)benzofuran-5-yloxy]methyl}phenoxy}pentanenitrile

Participants

Reaction Steps

Phosphorus oxychloride (245 mg) was dissolved in dimethylformamide (2 ml) and the solution was ice-cooled. To this solution was added 2-{2-{[2-(4-tert-butylthiazol-2-yl)benzofuran-5-yloxy]methyl}phenoxy]pentanamide (510 mg), and the mixture was stirred for two hours at room temperature. The reaction mixture was concentrated, diluted with water, and extracted with ethyl acetate. The organic layer was washed with brine, dried over magnesium sulfate, and concentrated to give 2-{2-{[2-(4-tert-butylthiazol-2-yl)benzofuran-5-yloxy]methyl}phenoxy}pentanenitrile (453 mg).
