Hydrochloric Acid → HCID 66276727, compound

Participants

Reaction Steps

6-Chloronicotinic acid (0.500 g, 3.17 mmol), powdered potassium hydroxide (0.712 g, 12.69 mmol) and 1,1,1-trifluoropropan-2-ol (0.724 g, 6.35 mmol) were combined in DMSO (12 mL) and heated in a sealed tube to 100 C for 18 h. The mixture was acidified to pH 1 by adding 2M hydrochloric acid. The mixture was then left to stand at room temperature overnight and the resultant precipitate filtered off, washed with water and dried under vacuum to afford the title compound as a cream solid (0.527 g, 71%). 1H NMR (500 MHZ, MeOH-d4) δ ppm 8.82 (1H, d), 8.29 (1H, dd), 6.94 (1H, d), 5.96 (1H, m) and 1.52 (3H, d).
