Procedure

Analogously to Example 1, 10 g of pyridine-2,5-dicarboxylic acid are converted into the acid chloride and this is reacted with 19.9 g of methyl (±)-mandelate. After extraction, working up is carried out by chromatography over silica gel with a mixture of toluene and ethyl acetate as the mobile phase.
