Reaction Conditions

Reaction Steps

26.8 g (0.1 mol) of 2-chloro-N-(2-chloro-3-pyridinyl)-3-pyridinecarboxamide were dissolved in 200 ml of dioxane, and the resulting solution was admixed with 21.4 g (0.362 mol) of propylamine. Thereafter, the mixture was shaken in a stainless steel pressure vessel at 150° C. for 6 hours. The reaction mixture was then evaporated in vacuo, and the residue was purified by column chromatography on silica gel, successively using dichloromethane/ethyl acetate 10/1 (v/v) and dichloromethane/cyclohexane/ethyl acetate 1/2/1 (v/v/v) as eluents. The product obtained by evaporation was a highly viscous resin that had a satisfactory quality for the following reaction.
