Reaction Conditions

Temperature	120 °C

Reaction Steps

A mixture of 4 g (22 mmol) N-(2-chloro-pyridin-4-yl)-N-methyl-acetamide and 2.8 g (22 mmol) 1-(2-propyl)-piperazine was heated to 120° C. for 24 h. The crude product was purified by flash column chromatography on silica elutingwith a gradient formed from heptane and ethyl acetate (0.1% NEt3) to yield after evaporation of the product fractions 2.5 g (41%) of the title compound as light brow oil. MS: (m/e): 277.2 (MH+).
