Versuchsvorschrift
A mixture of 1 g (9.16 mmol) 4-hydroxymethylpyridine, 0.44 g (11.0 mmol) sodium hydride (60% dispersion in oil) and 15 ml DMF is incubated for 20 min at 0° C. while stirring in a nitrogen atmosphere. At RT, 1 g (3.07 mmol) 1-chloro-4-(4-chloroanilino)phthalazine hydrochloride is added to the mixture, which is stirred for about 1 h at 50° C. and for 15 h at 80° C. Addition to the reaction mixture of a little water, evaporation under vacuum, recrystallization of the residue from methanol, and drying under HV yield the title compound with a water content of 3.36%; m.p. 139-141° C.; ESI-MS: (M+H)+=363.
