Reaction Steps

1,4-dichlorophthalazine (741 mg, 3.72 mmol), 1-tert-butyl 2-methyl piperazine-1,2-dicarboxylate (1.00 g, 4.09 mmol), N,N-diisopropylethylamine (0.972 mL), and 4-methyl-2-pentanone (6 mL) were heated at 120° for 16 hours. The solvent was removed and the residue purified by chromatography over silica using a gradient of hexanes/0-70% ethyl acetate. The compound was obtained as a white solid. MS (M+H)+=407.1.
