실험 절차

A mixture of 5-Chloro-2-phenyl-7,8,9,10-tetrahydro-imidazo[1,2-c]-quinazoline (200 mg), triethylamine (0.5 mL), and 100 mg of 10% palladium on carbon catalyst in 200 mL ethanol was hydrogenated at 30 psi for 4 hours. The reaction mixture was then filtered through celite, and the solvent was removed in vacuo. The resulting mixture was chromatographed using 30% ethyl acetate/hexane as eluant to yield 2-Phenyl-7,8,9,10-tetrahydro-imidazo[1,2-c]-quinazoline (Compound 42), m.p. 175°-181° C.
