실험 절차

A mixture of 0.511 g (2 mmol) 1-chloro-4-(4-pyridylmethyl)phthalazine, 1.273 ml (10 mmol) (S)-1phenylethylamine and 5 ml 1-butanol is stirred for 24 h at 110° C. The reaction mixture is evaporated under vacuum and the residue distributed between dichloromethane and 20% aqueous potassium carbonate solution. The organic phase dried over anhydrous sodium sulfate is evaporated in the RE and then under HV and the residue purified on silica gel by flash chromatography using dichioromethane/methanol (50:1). The product-containing fractions are dissolved in 5 ml methanol, acidified with 0.75 ml 3N methanolic HCl and evaporated under vacuum. After recrystallization of the residue from methanol/acetonitrile, drying of the crystallizate under HV (8 h, 100° C.) and equilibration for 15 h at 20° C. and in room atmosphere, title compound is obtained with a water content of 10.66%; m.p. 190° C. (decomp.); ESI-MS: (M+H)+=341; [a]D20=+42.1±0.8° (c=1.272%, methanol).
