Reaction Steps

This compound is prepared in a manner analogous to that of Step D of Example 4, using 1.7 grams (0.008 mole) of 2-amino-5-bromo-3-cyano-4-methylpyridine, 2.7 grams (0.012 mole) of 6-chloro-2,3-dihydro-2,2-dimethylbenzofuran-4-ylboronic acid, 4.3 grams (0.031mole) of potassium carbonate and 0.3 mL (catalyst) of tetrakis(triphenylphosphine)palladium(0) in 150 mL of toluene, yielding 2-amino-3-cyano-4-methyl-5-(6-chloro-2,3-dihydro-2,2-dimethylbenzofuran-4-yl)pyridine.
