When 3-amino-4-picoline is subjected to diazotization in fluoboric acid as in Example I-1, there is obtained 3-fluoro-4-picoline. Treatment of the latter intermediate with sodium amide as in Example I-1, gives 2-amino-5-fluoro-4-picoline. Following the procedure of Example I-15, but substituting 2-nitramino-5-fluoro-4-picoline, there is obtained 2-amino-5-fluoro-4-methyl-3-pyridinol.
