Versuchsvorschrift

A mixture of 4-(N-t-butoxycarbonylamino)nicotinic acid (2.72 g, 11.4 mmol), TFA (10 mL), and CH2Cl2 (20 ml) is stirred at room temperature for 12 h. The volatiles are removed under reduced pressure, and the resulting crude 4-amino nicotinic acid is used directly in the next reaction,
