2-Chloro-isonicotinic acid (5.10 g, 32.38 mmol) was dissolved in methanol (150 mL). Thionyl chloride (12 mL) was added. This suspension was stirred 5 h at 70° C. and concentrated in vacuo. The residue was dissolved in dichloromethane (250 mL) washed with a solution of 10% aqueous K2CO3 (2×150 mL) dried with MgSO4, filtered and evaporated. Methyl 2-chloropyridine-4-carboxylate SLA 07150 was obtained as a yellow solid (5.06 g, 91%).
