Phosphorus oxychloride → HCID 19603702, compound

Participants

Reaction Steps

Phosphorus oxychloride (0.14 ml) was added into N,N-dimethylformamide (0.86 ml) under ice-cooling. After 10 minutes, solution of 1-{[2-(4-tert-butylthiazol-2-yl)benzofuran-5-yl]methyl}indole-2-carboxamide (0.43 g) in N,N-dimethylformamide (5 ml) was added to the solution. And then the solution was stirred for several minutes at room temperature and poured into saturated sodium hydrogen carbonate aqueous solution. The resulting precipitates were collected by filtration and washed with water and air-dried to give 4-tert-butyl-2-{5-[(2-cyanoindol-1-yl)methyl]benzofuran-2-yl}thiazol (0.43 g).
