Reaction Steps

A mixture of N-isopropyl-2-[2-(3-methoxyphenyl)-4-oxo-6-perhydro-1,4-diazepin-1-yl-4H-quinazolin-3-yl]acetamide (EXAMPLE 2a) hydrochloride salt (50 mg, 0.103 mmol), ethyl bromide (22 mg, 0.21 mmol), and K2CO3 (43 mg, 0.31 mmol) in acetonitrile (5 mL) was heated to reflux for 24 h. The mixture was then cooled, filtered and concentrated in vacuo. The crude residue was purified by preparative HPLC to afford 2-[6-(4-ethylperhydro-1,4-diazepin-1-yl)-2-(3-methoxyphenyl)-4-oxo-4H-quinazolin-3-yl]-N-isopropylacetamide (EXAMPLE 4a) (5.1 mg, 0.010 mmol, 10%) as the hydrochloride salt.
