Procedure

This compound is prepared in a manner analogous to that of Step B of Example 9, using 1.3 grams (0.006 mole) of 3-amino-2-cyano-6-(trimethylsilylethynyl)pyridine and 0.9 gram (0.006 mole) of potassium carbonate in 50 mL of methanol, yielding 3-amino-2-cyano-6-ethynylpyridine. This reaction is repeated several times.
