Morpholine → 4-[5-Chloro-4-[(4-chlorophenylthio)-(2,5-difluorophenyl)methyl]pyridin-2-yl]morpholine

Participants

Reaction Steps

A 1,4-dioxane (1.0 ml) solution of the 2,5-dichloro-4-[(4-chlorophenylthio)-(2,5-difluorophenyl)methyl]pyridine (100 mg, 0.24 mmol) obtained in Example 54 and morpholine (200 μl) was stirred at 100° C. for 2 days under a nitrogen atmosphere. After cooling to room temperature, the reaction mixture was diluted with ethyl acetate (40 ml). The diluted mixture was washed with water and brine, dried and then concentrated under reduced pressure to give a residue. The resulting residue was purified by silica gel chromatography (hexane:ethyl acetate=5:1) to give the title compound (100 mg, 89%) as an oil.
