Reaction Steps

The above-described method (Example 2) was repeated to react 2-methoxyethyl 2-amino-5-bromo-3-methylbenzoate (5.00 g, 15.88 mmol) with copper cyanide (1.49 g, 16.67 mmol) in N-methylpyrrolidone at 170° C. for 6 hours. Following working up similar to Example 2 and additional extraction with ethyl acetate and washing with aqueous 5% ethylenediamine solution, 2-methoxyethyl 2-amino-5-cyano-3-methylbenzoate (0.45 g, 11.6% of theory, 95.6 area % LC) was obtained as a brown solid.
