Reaction Steps

To 70 ml of N,N-dimethylformamide, 3.00 g (19 mmol) of 6-chloronicotinic acid and 2.00 g (29 mmol) of 2-butyne-1-ol were dissolved, followed by adding 1.80 g (45 mmol) of 60% sodium hydride, stirring at room temperature for 1 hour and stirring at 140° C. for 3 hours. The reaction liquid was then poured in 150 ml of ice water, and acetic acid was added to make pH 5, followed by adding 50 ml of a saturated saline solution. The crystal precipitated was filtered, washed with cold water and hexane and dried to obtain 0.96 g (yield: 26%) of 6-(2-butynyloxy)nicotinic acid.
