Reaction Steps

7-Methoxy-8-(3-morpholin-4-ylpropoxy)-2,3-dihydroimidazo[1,2-c]quinazolin-5-amine (100 mg, 0.28 mol) was dissolved in DMF (3 mL), and 2-aminopyridine-4-carboxylic acid (38 mg, 0.28 mmol) was added. PYBOP (217 mg, 0.42 mmol) and diisopropylethylamine (0.15 mL, 0.83 mmol) were subsequently added, and the mixture was stirred at rt overnight. The mixture was purified by HPLC to give the title compound (50 mg, 37%). LC MS RT=1.02 min, MH+=480.3. 1H NMR (DMSO-d6) δ: 13.25 (1H, br s), 10.15 (1H, br s), 8.42 (1H, br s), 8.08 (1H, s), 8.06 (1H, d), 7.43 (1H, d), 7.75 (1H, s), 7.50 (1H, d), 7.38 (1H, dd), 4.50 (2H, dd), 4.35 (2H, br t), 4.27 (2H, dd), 4.01 (3H, s), 3.99 (2H, br s), 3.66 (2H, t), 3.50 (2H, d), 3.31 (2H, br t), 3.13 (2H, m), 2.25 (2H, m).
