Reaction Steps
A mixture of 2.0 g of the product of Step A in 20 ml of acetic anhydride was stirred at reflux for 3 hours and was cooled to room temperature overnight. The mixture was poured into a saturated sodium carbonate solution and the resulting mixture was extracted with chloroform. The organic phase was washed with sodium carbonate solution and with water, dried over magnesium sulfate and evaporated to dryness under reduced pressure. The residue was triturated with ether and was filtered to obtain 1.3 g of imidazo-[1,2-a]-quinoline-2-carbonitrile in the form of pale yellow crystals melting at 244°-246° C. after crystallization from a chloroform-ether mixture.
