医药
路线1：氨解反应
- 步骤: 向2L三颈烧瓶中加入4-氯-2-（甲硫基）嘧啶-5-羧酸乙酯（100g，0.43mol）、THF（500mL）和TEA（186mL，1.29mol）；分批加入氢氧化铵（28％水溶液，400mL），保持内部温度低于30℃；2小时后，加入水（1000mL），真空蒸馏除去THF；将所得固体过滤并在50℃下真空干燥，得到4-氨基-2-（甲硫基）嘧啶-5-羧酸乙酯（90g，99％）。
- 条件: With ammonium hydroxide; triethylamine In tetrahydrofuran; water at 30℃; for 2 h.
- 收率: 99%
