Example 4: To a mixed solution of 100 mL of 2% aqueous sodium hydroxide and 100 mL of dioxane containing 5-aminopentanoic acid (5.85 g, 0.05 mol), a solution of dioxane containing di-tert-butyl dicarbonate (10.9 g, 0.05 mol) was slowly added dropwise. The reaction mixture was stirred at room temperature for 18 h and then acidified with 1 N hydrochloric acid to pH 3. The acidified reaction mixture was extracted three times with dichloromethane. The organic layers were combined, washed sequentially with water and dried over sodium sulfate, and concentrated under reduced pressure to give 10.1 g (93.5% yield) of 5-(tert-butoxycarbonylamino)pentanoic acid as a white crystalline solid.
