Benzylamine → 1-Benzylamino-4-(4-pyridylmethyl)phthalazine

참여 물질

반응 조건

반응 단계

A mixture of 1.28 g (5 mmol) 1-chloro-4-(4-pyridylmethyl)phthalazine and 1.64 ml (15 mmol) benzylamine is stirred for 4 min at 90° C. under a nitrogen atmosphere. The reaction mixture is then distributed between dichloromethane and 20% aqueous potassium carbonate solution. The organic phase dried over anhydrous sodium sulfate is evaporated and the residue purified on silica gel by flash chromatography using acetate and acetate/methanol (20:1). Title compound is obtained after crystallization of the product-containing fractions from acetonitrile and drying under HV (8 h, 80° C.); m.p. 137-138° C.; ESI-MS: (M+H)+=327.
