Reaction Steps

4-[3-(tert-Butylcarbamoylmethyl)-2-(3-chlorophenyl)-4-oxo-3,4-dihydroquinazolin-6-yl]perhydro-1,4-diazepine-1-carboxylic acid tert-butyl ester (INTERMEDIATE VIII.1) (38.9 mg, 0.068 mmol) was treated with TFA:DCM (1:1 (v/v), 1 mL) and the solution stirred at room temperature for 40 min. The volatiles were removed in vacuo and the residue partitioned between DCM and 1 M NaOH (aq.). The organics were dried (Na2SO4) and concentrated in vacuo to yield N-tert-butyl-2-[2-(3-chlorophenyl)-4-oxo-6-perhydro-1,4-diazepin-1-yl-4H-quinazolin-3-yl]acetamide (EXAMPLE 1a) (27 mg, 0.046 mmol, 68%) as the trifluoroacetic acid salt.
