Reaction Conditions

Reaction Steps

The above nitrile (1.10 g, 5.68 mmol) was dissolved in H2SO4 (9.0 M, 6.0 mL) and heated to 120° C. for 8 h. The solution was cooled to rt and NaOH (˜2.0 g) was added slowly to neutralize the solution. The mixture was then diluted with an equal volume of saturate KH2PO4 and extracted several times with 25% 2-propanol in chloroform. The extracts were combined, dried over Na2SO4, filtered, and concentrated to provide 2-tert-butyl-5-methoxy-isonicotinic acid (1.09 g, 92%) as a pale brown solid which was utilized without further purification.
