Reaction Steps

A solution of (6-chloro-4-iodo-pyridin-3-yl)-carbamic acid tert-butyl ester (8.6 g, 24.3 mmol) dissolved in CH2Cl2 was treated with 4 N HCl/dioxane (100 mL) and stirred at room temperature for 2 hours. The reaction mixture was diluted with CH2Cl2 and washed with 2 N NaOH. The organic layer was dried over MgSO4 and concentrated to give the product as a solid (6.2 g, 100%).
