Reaction Steps

To a stirring mixture of (E)-ethyl 3-(2-amino-5-(trifluoromethoxy)phenyl)acrylate (2.2 mmol) in 4N HCl in dioxane (25 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. The product was extracted with EtOAc and used without further purification. Retention time (min)=1.804, method [1], MS (ESI) 230.1 (M+H).
