30 mg 6-Amino-4-(2-tert-butyl-5-methyl-2H-pyrazol-3-ylamino)-2-(4-tert-butyl-phenyl)-2H-phthalazin-1-one were dissolved in 0.5 ml methanol. 2 ml conc. HCl were added and the mixture was heated to 80° C. for 7 hrs. The mixture was evaporated under vacuum, the residue dissolved in dichloromethane and washed with sodium bicarbonate solution. Removal of the dichlormethane yielded 12 mg of the title product. 1H-NMR: (400 MHz, D6-DMSO) 11.75 (1H, br s), 8.75 (1H, br s), 8.00 (1H, d), 7.59 (2H, d), 7.46 (2H, d), 7.27 (1H, s), 7.05 (1H, d), 6.16 (br s, 2H), 2.17 (3H, s), 1.33 (9H, s); MS (ESI+)=389.22 (M+H)+.
