Reaction Steps

2-(6-(1,4-Diazepan-1-yl)-2-(4-fluoro-3-methoxyphenyl)-4-oxoquinazolin-3(4H)-yl)-N-isopropylacetamide (EXAMPLE 1i) (30 mg, 0.064 mmol), (tetrahydro-2H-pyran-4-yl)methyl 4-methylbenzenesulfonate (35 mg, 0.128 mmol) and DIPEA (17 mg, 21 μl, 0.128 mmol) were dissolved in DMF (1 mL) and stirred at room temperature overnight. Purification by preparative HPLC afforded 2-{2-(4-fluoro-3-methoxyphenyl)-4-oxo-6-[4-(tetrahydropyran-4-ylmethyl)perhydro-1,4-diazepin-1-yl]-4H-quinazolin-3-yl}-N-isopropylacetamide (EXAMPLE 11a) (5 mg, 0.0088 mmol, 14%).
