Reaction Steps

A mixture 6-bromo-4-chloro-2H-phthalazin-1-one (153 mg, 0.590 mmol), 2-(aminomethyl)pyridine (0.066 mL, 0.646 mmol), Pd2(dba)3 (49 mg, 0.0535 mmol), rac-BINAP (113 mg, 0.181 mmol) and NaOtBu (160 mg, 1.665 mmol) in DMA (5 mL) was heated at 85° C. for 1.5 h. The mixture was allowed to cool, diluted with EtOAc and washed with water. The organic layer was washed with sat.aq. NaHCO3, brine and dried (Na2SO4). Chromatography on silica (EtOAc/hexanes) afforded 4-chloro-6-[(pyridin-2-ylmethyl)-amino]-2H-phthalazin-1-one (3 mg) as a yellow brown solid, 1H (400 MHz, d6-DMSO) δ: 4.53 (d, 2H), 6.84 (s, 1H), 7.18 (dd, 1H), 7.28 (m, 1H), 7.38 (d, 1H), 7.75 2H), 7.92 (d, 1H), 8.55 (d, 1H), 12.35 (s, 1H) ppm; m/z (M+1) 286.99.
