Reaction Conditions

Reaction Steps

To a stirring mixture of (E)-ethyl 3-(2-amino-4-fluoro-5-(trifluoromethyl)phenyl)acrylate in 4N HCl in dioxane (10 mL) was added concentrated HCl (2 mL). The resulting mixture was warmed to 100° C. overnight. The reaction mixture was cooled to rt and then slowly quenched with a cold saturated NaHCO3 solution until pH>7. A normal aqueous extraction with EtOAc was followed. The crude mixture was taken directly to the next reaction without further purification. Retention time (min)=1.887, method [1], MS(ESI) 232.0 (M+H).
