To a solution of 6-bromo-3-[(1S,2S)-2-hydroxycyclohexyl]-10-methyl-7,8,9,10-tetrahydropyrido[3,2-h]quinazolin-4(3H)-one (40 mg, 0.10 mmol) in THF (0.4 mL) at 0° C. was added (2-chloro-5-pyridyl)methylzinc chloride (0.5 M in THF, 408 μL, 0.20 mmol) and Pd(PtBu3)2. The mixture was warmed to rt and stirred for 30 min. The resulting solution was quenched with water and extracted with CH2Cl2. The combined extracts were dried (Na2SO4) and concentrated. Purification by silica gel chromatography (0-5% MeOH/CH2Cl2) afforded 6-[(6-chloropyridin-3-yl)methyl]-3-[(1S,2S)-2-hydroxycyclohexyl]-10-methyl-7,8,9,10-tetrahydropyrido[3,2-h]quinazolin-4(3H)-one in pure form: 1H NMR (400 MHz, CD3OD); 1H NMR (400 MHz, CDCl3) 8.20 (d, J=2.3 Hz, 1H), 8.03 (s, 1H), 7.59 (s, 1H), 7.33 (dd, J=2.3, 8.2 Hz, 1H), 7.17 (d, J=8.2 Hz, 1H), 4.51 (m, 1H), 3.96 (s, 2H), 3.90 (m, 1H), 3.12 (t, J=5.2 Hz, 2H), 3.08 (s, 3H), 2.56 (t, J=6.5 Hz, 2H), 2.24-2.15 (m, 2H), 2.00-1.92 (m, 2H), 1.89-1.75 (m, 4H), 1.55-1.37 (m, 2H); HRMS (MH+) calcd for C24H28ClN4O2 439.1895. found 439.1894.
