الإجراء التجريبي

Meanwhile, the 4-methylbenzoyl chloride acylating agent was prepared by suspending 3.314 g (24.3 mmol) of ρ-toluic acid in 200 ml benzene. To this solution was added 2.0 equiv. (4.25 ml) of oxalyl chloride, dropwise via a pressure-equalizing dropping funnel at O° C. DMF (2-3 drops) was added to the reaction mixture catalytically and the ice bath was removed. The progress of the reaction was monitored via infrared spectroscopy. The solvent was removed by rotary vacuum evaporation and the residual oil was pumped down under high vacuum overnight.
