Reaction Steps
1,4-dichlorophthalazine (1.0 g, 5 mmole) and trans-2,5-dimethyl piperazine were combined in a reaction vial and heated to 130° C. for 3 h with stirring. After cooling to room temperature, the solid residue was dissolved in 150 mL of dichloromethane and washed with 1×20 mL of 1:1 saturated NaHCO3 solution:H2O and 1×20 mL of saturated NaCl solution. The organic phase was dried over MgSO4, filtered, and concentrated. Purification by column chromatography (100:5:1 dichloromethane:methanol:triethylamine) afforded 1-chloro-4-(trans-2,5-dimethylpiperazin-1-yl)phthalazine. MS (M+H)+=277.1.
