実験手順

A suspension of 5-(4-fluorophenyl)-4-(pyridin-4-yl)isoxazole (5.35 g) in 1N sodium hydroxide aqueous solution (50 ml) was stirred for one hour at 60° C. The solution was cooled and adjusted to pH 6 with concentrated hydrochloric acid. The separated solid was collected, washed with water, and dried to give 3-(4-fluorophenyl)-3-oxo-2-(pyridin-4-yl)propanenitrile (5.27 g).
