実験手順
7-Methoxy-8-{[4-(methylsulfonyl)benzyl]oxy}-2,3-dihydroimidazo[1,2-c]quinazolin-5-amine (Step 1, 76 mg, 0.19 mmol) was dissolved in DMF (5 mL), and 2-aminopyrimidine-5-carboxylic acid (40 mg, 0.29 mmol) was added. PyBOP (152 mg, 0.29 mmol) and diisopropylethylamine (0.15 mL, 0.85 mmol) were subsequently added. The mixture was stirred at it overnight, during which a tan solid precipitated. The DMF was removed under reduced pressure and the residue purified via silica gel chromatography (0-3% MeOH/CH2Cl2+0.1% Et3N). The solvent was evaporated under reduced pressure, the residue triturated in water (5 mL), collected by vacuum filtration, then washed with acetone. High vacuum drying gave the title compound (12 mg, 12%): HPLC MS RT=2.06 min, MH+=522.1; 1H NMR (DMSO-d6+2 drops TFA-d) δ: 3.22 (3H, s), 4.00 (3H, s), 4.19-4.25 (2H, m), 4.48-4.55 (2H, m), 5.53 (2H, s), 7.53 (1H, d), 7.77 (2H, d), 7.97-8.03 (3H, m), 9.06 (2H, s).
