Reaction Steps

Salicylic acid (5.0 g, 36.2 mmol) was suspended in dry hexane (40 ml) and thionyl chloride (4.52 g, 38 mmol) was added under nitrogen atmosphere followed by one drop of pyridine. The mixture was refluxed for two hours while stirring. The clear yellow solution was cooled and concentrated in vacuum, giving a dense oil to be used in the next step.
