Methanol → 5-Methoxy-2-(2-fluorophenyl)-7,8,9,10-tetrahydro-imidazo[1,2-c]-quinazoline

Participants

Reaction Steps

To 10 mL anhydrous methanol was added 100 mg of sodium, and the mixture was stirred to ensure all the sodium had dissolved. Next, 5-Chloro-2-(2-fluorophenyl)-7,8,9,10-tetrahydro-imidazo[1,2-c]-quinazoline (200 mg) was added and the mixture refluxed for 1 h. To this mixture was added 2 mL of acetic acid and the solvent was then removed under reduced pressure. The resulting solid was recrystallized from ethanol and collected to yield 5-Methoxy-2-(2-fluorophenyl)-7,8,9,10-tetrahydro-imidazo[1,2-c]-quinazoline (Compound 37), m.p. 160°-161° C.
