実験手順

A mixture of 0.5 g (1.5436 mmol) 1-chloro-4-(4-chloroanilino)phthalazine hydrochloride (for preparation see J. Chem. Soc. 1948, 777-782) and 2 g (18.50 mmol) 4-aminomethylpyridine is stirred for 36 h at 90° C. and then purified by means of flash chromatography on silica gel with a particle size of 0.04-0.06 mm using acetate and acetate/methanol (20:1). Evaporation of product-containing fractions, recrystallization of the residue from methanol, and drying of the crystallizate under HV yield the title compound; m.p. 233-236° C.; ESI-MS: (M+H)+=362.
