실험 절차
This compound is prepared in a manner analogous to that described in Example 1, Step 1, for pyridine-2-carboxylic acid ethyl ester, but instead 4-ethoxy-pyridine-2-carboxylic acid ethyl ester from Example 17 is used. The yellowish crude product is used for further syntheses without special purification steps. IR (cm−1): 1557 (vs); 1469 (w); 1436 (w); 1300 (m); 1207 (m); 1186 (m); 1035 (m); 818 (m).
