実験手順: N-(2-Fluorophenyl)cinnamamide (97.2 g, 403 mmol) was combined with AlCl3 (161 g, 1209 mmol) and the solids were thoroughly mixed. The dry mixture was heated to 160° C. for 100 minutes. The reaction was cooled and quenched by addition of ice. A beige solid formed after complete dispersion of the dark solids and this was stirred overnight. The beige solid was filtered and air-dried overnight to provide the desired product as a free-flowing solid (69.8 g). the solids were thoroughly mixed The reaction was cooled quenched by addition of ice A beige solid formed after complete dispersion of the dark solids The beige solid was filtered air-dried overnight
