The resulting mixture was stirred at room temperature for overnight. The mixture was diluted with methylene chloride, and was washed one time with water. The organic phase was dried over potassium carbonate and concentrated by rotary evaporation. The resulting sample was dried under vacuum gave a light yellow solid (1.18 g, 97%).
