実験手順

In a round bottom flask, (10 g) Benzophenone in 20 ml methanol was taken. 12 ml (2 equiv.) trimethyl orthoformate was added into the reaction mixture in a single lot and the reaction mixture was stirred at 25-30° C. 3-4 drop perchloric acid (HClO4 as a catalyst) was added and reflux it for 9 hr. After completion of the reaction, the reaction mass was dumped into water. Subsequently, the reaction mass was stirred for 15 min, filtered it and wash the solid mass with water to obtain white solid product.
