反応手順
A mixture of 7.73 g of p-toluyl chloride, 5.91 g of diethyl carbonate, and 0.85 g of TBPB in 25 ml of sulfolane was heated at 170° C. under reflux. After 44 hours, the reaction mixture was added to 200 g of crushed ice and this was extracted twice with 25-ml portions of hexane. The combined extracts were dried over anhydrous Na2SO4 and distilled to obtain 6.4 g (78 percent yield) of ethyl p-toluate, b.p. 120°-1° C./20 mm.
