Reaction Steps

7-Methoxy-8-(3-morpholin-4-ylpropoxy)-2,3-dihydroimidazo[1,2-c]quinazolin-5-amine (100 mg, 0.22 mol) was dissolved in DMF (5 mL), and Intermediate B (46 mg, 0.33 mmol) was added. PYBOP (173 mg, 0.33 mmol) and diisopropylethylamine (0.16 mL, 0.89 mmol) were subsequently added, and the mixture was stirred at rt overnight. EtOAc was added, and the solids were isolated by vacuum filtration to give the title compound (42.7 mg, 40%): HPLC MS RT=1.09 min, MH+=481.2; 1H NMR (DMSO-d6+2 drops TFA-d) δ: 9.01 (2H, s), 8.04 (1H, d), 7.43 (1H, d), 4.54 (2H, m), 4.34 (2H, br t), 4.23 (2H, m), 4.04 (2H, m), 4.00 (3H, s), 3.65 (2H, br t), 3.52 (2H, m), 3.31 (2H, m), 3.18 (2H, m), 2.25 (2H, m).
