Procedure

2-(E-2-Carboxymethylethenyl)-3-dodecyloxy-6-(hydroxymethyl)pyridine (250 mg, 0.662 mmol) was dissolved in dry toluene (10 mL) under an argon atmosphere and cooled to 0∞C. Thionyl chloride (0.50 mL 6.85 mmol) was slowly added and the solution was stirred at 0∞C for 30 minutes followed by 1 h at room temperature. The solvent and excess thionyl chloride were removed at reduced pressure. The crude hydrochloride salt was then used directly in the next step without further purification.
