    by the rate of hydrolysis of the two diastereomeric esters. The second synthesis proved to be more efficient and used a novel nucleophilic aromatic substitution of a fluoroindazole with the anion of a tertiary nitrile. Another key element of the route was a selective Pinner reaction of a secondary nitrile in the presence of a tertiary nitrile.
