Procedure

Ethyl 2-butyl-6-chloronicotinate (395 mg, 1.63 mmol) was stirred in methanol (10 ml) and 2M sodium hydroxide (2 ml, 4 mmol) was added. The solution was stirred at room temperature for 16 hours. The solvent was evaporated and the residue taken up in ice/water (10 ml) and acidified with 2M HCl. The milky solution was extracted with dichloromethane (2×15 ml) and the combined extracts were dried over MgSO4, filtered and evaporated, trituration with isohexane gave 2-butyl-6-chloronicotinic acid (300 mg, 86%) as a white solid.
