Versuchsvorschrift

N-[7-Hydroxy-8-(3-morpholin-4-ylpropoxy)-2,3-dihydroimidazo[1,2-c]quinazolin-5-yl]nicotinamide (Intermediate H, 0.09 g, 0.20 mmol) was suspended in DMF (2.0 mL) and NaH (0.02 g, 0.30 mmol, 60%) were added. After 20 min at rt 1-(chloromethyl)-4-(methylsulfonyl)benzene (0.06 g, 0.30 mmol) was added and the mixture was stirred at it for 16 h. The DMF was evaporated under reduced pressure and the residue triturated with a mixture of −10% MeOH in CH2Cl2 (4 mL). The mixture was vacuum filtered and the solids were washed well with CH2Cl2. The filtrate was concentrated under reduced pressure, and the residue purified via silica gel chromatography (0-6% MeOH/CH2Cl2). The fractions were combined, and the solvent was evaporated under reduced pressure. Drying under high vacuum gave the title compound (0.087 g, 70%): TLC (5% MeOH/CH2Cl2): Rf=0.47; HPLC MS RT=0.55 min, [M+Na]+=641; 1H NMR (DMSO-d6+2 drops TFA-d) δ: 2.21-2.35 (2H, m), 3.05-3.17 (2H, m), 3.22 (3H, s), 3.31 (2H, m), 3.42-3.52 (2H, m), 3.60-3.72 (2H, m), 3.94-4.04 (2H, m), 4.29 (2H, m), 4.39 (2H, t), 4.56 (2H, m), 5.37 (2H, s), 7.52 (1H, d), 7.72 (1H, dd), 7.85 (2H, d), 8.01 (2H, d), 8.10 (1H, d), 8.66 (1H, d), 8.89 (1H, dd), 9.43 (1H, s).
