Reaction Conditions

Reaction Steps

To a solution of 10 g 6-Amino-nicotinic acid in 100 mL MeOH, 0.8 mL concentrated H2SO4 were added and the mixture was heated to 60° C. for 12 h. Then the reaction mixture was concentrated under reduced pressure. After addition of 50 mL ice water the mixture was brought to pH 8 by addition of K2CO3. The aqueous phase was extracted with ethyl acetate (3×100 ml) and the combined organic layers were dried over MgSO4. Removal of the solvent yielded 5.5 g of the desired product which was subjected to the following reaction without further purification.
