Reaction Steps

5-Cyclohex-1-enyl-6-(2,2,2-trifluoroethoxy)nicotinic acid methylester (0.03 g, 95.2 μmol) was combined with THF (0.3 mL) and water (0.15 mL) to give a light yellow solution. Lithium hydroxide hydrate (7.99 mg, 190 μmol) was added under argon. The reaction mixture was stirred at room temperature overnight, poured into 2 mL 2 M HCl and extracted with i-propyl acetate (2×20 mL). The organic layers were combined, dried with Na2SO4 and concentrated in vacuo to give the title compound (30 mg, quant) as white solid that was used in the subsequent reactions without further purification; MS (ESI) 300.2 (M−H)−.
