Reaction Steps

To 20 mL of 1N NaOH was added 9-Carboethoxy-2-(2-fluorophenyl)-7,8,9,10-tetrahydro-imidazo[1,2-c]-quinazolin-5(6H)-one (400 mg). After the solid dissolved, the mixture was stirred for 40 minutes at 60° C., cooled and the pH adjusted to 3 with concentrated HCl. The solid was collected and dried to yield 9-Carboxy-2-(2-fluorophenyl)-7,8,9,10-tetrahydro-imidazo[1,2-c]-quinazolin-5(6H)-one (Compound 17), m.p.>325° C.
