Reaction Steps

Using an analogous procedure to that described in Example 150, 248.7 mg (1 mmol) of 4-chloro-6,7-dimethoxy-3-quinolinecarbonitrile, 294.4 mg (2.0 mmol) of 2-methyl-5-aminobenzimidazol and 115.6 mg (1 mmol) of pyridine hydrochloride in 10 mL of 2-ethoxyethanol was refluxed for 4 hr. The work up gave 220.2 mg (61.3%) of the product as a sand color solid, m.p. 207° C. (dce.), mass (electrospray, m/e): M+H 359.9. HRCIMS: calcd 359.138 for C20H17N5O2 (M+), obsd 359.1403.
