実験手順
To 10 mL of trifluoroacetic acid was added 9-(t-Butoxycarbonylamino)-2-(2-fluorophenyl)-7,8,9,10-tetrahydro-imidazo[1,2-c]-quinazolin-5(6H)-one (100 mg). After the solid dissolved, the solution was stirred for 20 minutes and the TFA removed in vacuo. To the residue was added 10 mL of water followed by sufficient saturated aqueous sodium bicarbonate to neutralize the mixture. The mixture was subsequently cooled and the solid collected to yield 9-Amino-2-(2-fluorophenyl)-7,8,9,10-tetrahydro-imidazo[1,2-c]-quinazolin-5(6H)-one (Compound 29), m.p.>325° C.
