실험 절차

To 10 mL of anhydrous t-butanol was added 9-Carboxy-2-(2-fluorophenyl)-7,8,9,10-tetrahydro-imidazo[1,2-c]-quinazolin-5(6H)-one (327 mg), diphenylphosphorylazide 275 mg), and triethylamine (100 mg). The resulting mixture was refluxed for 14 hours and the solvent removed in vacuo. The mixture was then triterated with 10 mL hot methanol and the resultant solid was collected, washed with ethyl acetate, and dried to yield 9-(t-Butoxycarbonylamino)-2-(2-fluorophenyl)-7,8,9,10-tetrahydro-imidazo[1,2-c]-quinazolin-5(6H)-one (Compound 28), m.p.>325° C.
