Reaction Steps

To methanol (50 mL) were added concentrated sulfuric acid (25 mL) and 2-amino-6-chloro-nicotinic acid (4.3 g, 25 mmol) described in Preparation Example A-1 (or A-4) on an ice bath, which was stirred at 70° C. for 5 hours. After cooling, an aqueous solution of sodium bicarbonate (90 g) was added to neutralize. The resulting solid was filtered to obtain the title compound (3.2 g, 17 mmol, 68%) as a light brown solid.
