実験手順

A mixture of 1.22 g (3 mmol) 1-(3-brom-4-methyl-anilino)-4-(4-pyridyl-methyl)-phthalazine (expl. 14 h) and 336 mg (3 mmol) potassium-tert.butylate in 10 ml DMSO is stirred in an open vessel for 10 days at RT. Then the yellow mixture is diluted with EtOAc and water, the aqueous layer separated off and extracted twice with EtOAc. The organic phases are washed twice with water and brine, dried (Na2SO4) and partly concentrated. After adding 10 g of SiO2, the residue is dried in vacuo and the resulting powder put on top of a SiO2 -column. Eluation with dichloromethane/EtOAc (5:1→1:1→EtOAc) yields [4-(3-brom-4 -methyl-anilino)phthalazin-1-yl](pyridin-4-yl)ketone (A) followed by [4-(3-brom-4-methyl-anilino)phthalazin-1-yl](pyridin-4-yl)methanol (B). A: m.p. 249-250° C.; FAB MS (M+H)+=419/421. B: m.p. 240° C.; FAB MS (M+H)+=421/423.
