Reaction Steps

4-Bromo-2-isopropyl-7-methylamino-2H-phthalazin-1-one (0.13 g, 0.44 mmol) was dissolved in DMF (5 ml). To this was added NaH (60%, 0.053 g, 1.3 mmol) as a suspension in DMF (2 ml). The mixture was stirred at RT for 30 min then 4-(2-chloro-ethyl)-morpholine (0.12 g, 0.66 mmol) was added in one portion as a solution in DMF (I ml) and the reaction mixture was heated to 70° C. for 24 hours. After this time, the reaction mixture was cooled to RT and water (10 ml) was added cautiously, the mixture was extracted with EtOAc (3×10 ml), the organic layers were combined, dried (MgSO4), filtered and concentrated under vacuum. Flash column chromatography (elution: 95% EtOAc, 5% MeOH) gave the title compound (0.051 g, 30% yield) as a white solid. 1H-NMR: (400 MHz, CDCl3), 7.72 (1H, d), 7.49 (1H, s), 7.16 (1 H, d), 5.42-5.29 (1H, m), 3.73-3.67 (4H, m), 3.66-3.59 (2H, t), 3.15 (3H, s), 2.61-2.54 (2H, m), 2.53-2.46 (4H, m), 1.41 (6H, d).
