Reaction Steps

Concentrated sulfuric acid (25 mL) and 2-amino-6-chloro-nicotinic acid (4.3 g, 25 mmol) described in Manufacturing Example 26-1-1 were added to methanol (50 mL) on an ice bath, and stirred at 70° C. for 5 hours. The reaction mixture was cooled and then neutralized by addition of aqueous sodium hydrogen carbonate (90 g) solution. The precipitated solids were filtered to obtain the title compound (3.2 g, 17 mmol, 68%).
