Procedure

A mixture of 5-ethoxymethyl-2-methyl-N-(2-pyrrolidin-1-yl-ethyl)-benzene-1,3-diamine hydrochloride (430 mg, 1.55 mmol), 1-chloro-4-oxo-3,4-dihydro-phthalazine-6-carboxylic acid and 4-chloro-1-oxo-1,2-dihydro-phthalazine-6-carboxylic acid (331 mg, 1.476 mmol), N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (863 mg, 4.50 mmol), NEt3 (0.82 mL, 5.904), 1-hydroxybenzotriazole hydrate (259 mg, 1.919 mmol) and anhydrous DMF was stirred at room temperature for 2.5 h. The reaction mixture was filtered through celite, rinsed with CH2Cl2 and concentrated. Preparatory HPLC afforded 1-chloro-4-oxo-3,4-dihydro-phthalazine-6-carboxylic acid [5-ethoxymethyl-2-methyl-3-(2-pyrrolidin-1-yl-ethylamino)-phenyl]-amide formic acid salt (72 mg) as an orange solid.
