実験手順
117 g (0.27 mol) of ethyl 6-[(5-chloro-2-{[(4-chloro-2-fluorophenyl)methyl]oxy}phenyl)-methyl]-2-pyridinecarboxylate were dissolved in ethanol (1 litre) (heating required) and 2M sodium hydroxide (200 ml) was added while still hot. Left to crystallise, and when at room temperature was diluted with an equal volume of water. After one hour at room temperature the solid was filtered off and washed with ethanol/water (1:3). MLS (mother liquors) were evaporated to remove ethanol, the solid was filtered off and the two lots were combined and washed with water and ether. Dried in a vacuum oven for 16 hours at 40° C. and 3 days at 60° C. Yield 110.5 g.
