Reaction Steps

To a mixture of 3.0 g of 6-chloronicotinic acid and 111 ml of THF was added 6.4 g of potassium tert-butoxide, followed by heating under reflux for 1 day. The reaction solution was poured into water, neutralized with citric acid, and then extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate and then concentrated under reduced pressure to obtain 2.16 g of 6-tert-butoxynicotinic acid.
