Participants

Reaction Steps

To a roundbottom flask is added 3-chloro-4,5-dimethyl-6-piperazin-1-yl-pyridazine (1 g, 4.41 mmol), 2-chloro-4-trifluoromethyl-pyrimidine-5-carboxylic acid methyl ester (2.12 g, 8.82 mmol) and diisopropylethylamine (2.3 mL, 13.23 mmol) in a dioxane (9 mL) solution and stirred for 18 h at room temperature. Filter the reaction mixture and rinse with water and ethylacetate to give 1.35 g of 2-[4-(6-chloro-4,5-dimethyl-pyridazin-3-yl)-piperazin-1-yl]-4-trifluoromethyl-pyrimidine-5-carboxylic acid methyl ester (71%).
