実験手順

To a solution of 2,4-dichloro-6-phenylpyrimidine (224 mg, 1 mmol) in 1 mL of 1,4-dioxane was added 300 uL of hydrazine hydrate. Stirring was continued at room temperature and the reaction monitored by thin layer chromatography (30% ethyl acetate/hexanes). When the starting material was consumed, 2 mL of water was added and the resultant precipitate was collected on a filter to afford 2-chloro-4-hydrazinyl-6-phenylpyrimidine as a yellow solid. The damp solid was suspended in 2 mL of ethanol, to which was added 220 mg of 4-trifluoromethoxybenzaldehyde. Within 5 minutes the solution became clear and then reprecipitated material. The product, 2-chloro-4-phenyl-6-(2-(4-(trifluoromethoxy)benzylidene)hydrazinyl)pyrimidine (XX), was collected by filtration and dried to afford 150 mg of a solid. ESI/MS 392.973, 395.002 (M+H).
