92% | With sodium hydroxide; In tetrahydrofuran; at 20℃; for 4h;Inert atmosphere; | A mixture of 10.2 g of 2,4-dichlorothieno-[2,3-d]-pyrimidine 7a, 120 mL 1 N NaOH and 20 mL of THF was stirred at room temperature under N2 for 4 h. The solution was then chilled and adjusted to pH 5 with AcOH. The resulting precipitate was collected, washed with water and dried to afford 8a as a solid (8.5 g, yield 92percent). MS (ESI) C6H3ClN2OS [M - H]- 185.1. |
