Procedure

Dissolve 2-chloro-5-(methyl-propylcarbamoyl)-nicotinic acid methyl ester (96 mg, 0.35 mmol) in 1 N sodium hydroxide (0.71 mL, 0.71 mmol) and methanol (2 mL). Stir at room temperature for 2 h. Concentrate organic and redissolve the residue in water (15 mL). Wash with dichloromethane (3×10 mL), acidify the aqueous layer with 1 N HCl to about pH=2. Extract with dichloromethane, dry (sodium sulfate) and concentrate to give the crude title product which is used in the next step without further purification.
