Mesitylene → HCID 21200188, compound

Participants

Reaction Steps

A 250-mL reaction flask fitted with a magnetic stirrer and a condenser is charged with 21.0 g (0.070 mol) of the product of Example 15, 100 mL of mesitylene and 9.30 g (0.070 mol) of aluminum chloride. The mixture is refluxed for three days. The mixture is then poured onto ice and the phases are separated. The organic phase is dried over anhydrous sodium sulfate and the solvent is removed under reduced pressure to give a brown resin. The crude resin is recrystallized from ligroin to give 7.9 g of the title compound as a white powder melting at 135-143° C.
