Procedure

To 100 mL of anhydrous tetrahydrofuron was added 9-(N,N-Dimethylcarbamyl)-2-(2-fluorophenyl)-7,8,9,10-tetrahydro-imidazo[1,2-c]-quinazolin-5(6H)-one (70 mg). The mixture was refluxed until the solid had completely dissolved. Refluxing was ceased and 100 mg of lithium aluminum hydride was added to the solution. This mixture was allowed to stand for 20 min before being quenched with ethyl acetate. The quenched reaction mixture was filtered through celite and the solvent removed in vacuo to yield an oil. The oil was then dissolved in 5 mL of ethyl acetate and to this ethyl acetate solution was added 1 mL of HCl saturated ethyl acetate. A solid precipitated which was collected and dried to yield 9-(N,N-Dimethylaminomethyl)-2-(2-fluoropenyl)-7,8,9,10-tetrahydro-imidazo[1,2-c]-quinazolin-5(6H)-one monohydrochloride (Compound 24), m.p.>325° C.
