4-[3-(Isopropylcarbamoylmethyl)-2-(3-methoxyphenyl)-4-oxo-3,4-dihydroquinazolin-6-yl]perhydro-1,4-diazepine-1-carboxylic acid tert-butyl ester (INTERMEDIATE VII.1) (50 mg, 0.091 mmol) was treated with 4 N HCl/MeOH (10 mL) and the resulting solution was stirred at room temperature for 2 h. The reaction mixture was concentrated in vacuo to afford N-isopropyl-2-[2-(3-methoxyphenyl)-4-oxo-6-perhydro-1,4-diazepin-1-yl-4H-quinazolin-3-yl]acetamide (EXAMPLE 2a) (40 mg, 0.091 mmol, 100%) as the hydrochloride salt. Data for N-isopropyl-2-[2-(3-methoxyphenyl)-4-oxo-6-perhydro-1,4-diazepin-1-yl-4H-quinazolin-3-yl]acetamide (EXAMPLE 2a) (EXAMPLE 2a) hydrochloride salt: MS (ESI) m/z: 450 ([M+H]+)
