실험 절차

To a solution of 5-(5-phenyl-4-((pyridin-2-ylmethyl)amino)phthalazin-1-yl)nicotinic acid (0.200 g, 0.461 mmol) in DMF (5 mL) was added HATU (0.526 g, 1.38 mmol) at ambient temperature. DMAP (0.169 g, 1.38 mmol) was added followed by (2,2-dimethyl-1,3-dioxolan-4-yl)methanamine (0.0610 g, 0.461 mmol, commercial) and the contents were stirred at ambient temperature for 16 h. The reaction mixture was concentrated under reduced pressure and the residue was diluted with water. The reaction mixture was extracted with EtOAc. The organic layer was dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure. The resulting residue was purified by combiflash (REDISEP®, silica gel, 12 g, 50% EtOAc/hexanes) to obtain N-((2,2-dimethyl-1,3-dioxolan-4-yl)methyl)-5-(5-phenyl-4-((pyridin-2-ylmethyl)amino) phthalazin-1-yl)nicotinamide (0.0300 g, 11.9%) as an off-white solid. LCMS (Condition 7): retention time 1.76 min, [M+1]=547.2. HPLC (Condition 24): retention time 7.68 min, Purity 96.10%. 1H NMR (400 MHz, DMSO-d6) δ 1.27 (s, 3H), 1.36 (s, 3 H), 3.31-3.51 (m, 2 H), 3.74 (dd, J=5.6 Hz, J=8.4 Hz, 1 H), 4.03 (dd, J=6.0 Hz, J=8.4 Hz, 1 H), 4.26 (m, 1 H), 4.66 (d, J=4.0 Hz, 2 H), 6.33 (dd, J=4.0 Hz, J=4.4 Hz, 1 H), 7.22 (dd, J=5.2 Hz, J=6.4 Hz, 1 H), 7.29 (d, J=6.8 Hz, 1 H), 7.50-7.59 (m, 5 H), 7.69-7.73 (m, 2 H), 7.84 (dd, J=1.6 Hz, J=8.0 Hz, 1 H), 7.93 (dd, J=7.2 Hz, J=8.0 Hz, 1 H), 8.23 (d, J=4.8 Hz, 1 H), 8.51 (t, J=2.0 Hz, 1 H), 8.94 (dd, J=5.6 Hz, J=6.0 Hz, 1 H), 9.0 (d, J=2.0 Hz, 1H), 9.16 (d, J=2.0 Hz, 1 H).
