Reaction Conditions

Reaction Steps

A mixture of 0.511 g (2 mmol) 1-chloro-4-(4-pyridylmethyl)phthalazine and 0.576 ml (6 mmol) 4-fluoroaniline is heated for 2 h at 90° C. The residue is then distributed between acetate and 20% aqueous potassium carbonate solution. The organic phase washed with water and dried over sodium sulfate is evaporated and the residue purified on silica gel by flash chromatography using acetate/methanol mixtures (50:1 and 25:1). Title compound is obtained after crystallization of the product-containing fractions from acetonitrile and drying under HV (6 h, 100° C.); m.p. 129-131° C.; ESI-MS: (M+H)+=331.
