Procedure

A mixture of 0.3 g (1.173 mmol) 1-chloro-4-(4-pyridylmethyl)phthalazine (for preparation see German Auslegeschrft no. 1 061 788 [published 23.07.1959]), and 0.483 g (3.52 mmol) 4-ethoxyaniline is heated for 30 min at 90° C. The cooled reaction mixture is distributed with thorough stirring between a dichloromethane/methanol mixture (18:1) and saturated aqueous sodium carbonate solution. The organic phase washed with water and brine is dried over anhydrous sodium sulfate and evaporated under vacuum. Title compound is obtained after recrystallization of the residue from acetate/methanol and acetonitrile; m.p. 223-224° C.; ESI-MS: (M+H)+=357.
