Participants

Reaction Steps

To a solution of 2-chloro-6-(trifluoromethyl)isonicotinic acid (0.15 g, 665 μmol, prepared according to F. Cottet, M. Schlosser, Eur. J. Org. Chem. 2004, 18, 3793-3798) in methanol (2 mL) sodium methoxide (79.0 mg, 1.46 mmol) was added and the reaction refluxed for 5 hours. Another 287 mg (5.32 mmol) sodium methoxide was added and the white suspension was stirred at reflux temperature overnight. After 23 hours the suspension was allowed to cool to room temperature and was poured on saturated 1M HCl solution and EtOAc and the layers were separated. The aqueous layer was extracted twice with EtOAc. The organic layers were washed once with brine, dried over MgSO4, filtered and evaporated to give the desired compound as a colorless solid (0.133 g; 90%). MS (ESI): m/z=220.02 [M−H]−.
