Versuchsvorschrift

To a stirred solution of 2-(trifluoromethyl)phenol (50.0 g, 0.31 mol) and progargyl bromide (44.0 g, 0.37 mol) in ACN (500 mL) was added K2CO3 (51.0 g, 0.37 mol) and the mixture was stirred overnight at rt, concentrated, diluted with water and extracted with Et2O. The combined organic layers were dried over Na2SO4, filtered, concentrated and purified by CC (PE/EA=40/1) to give compound P33a (59.7 g, 97%) as an oil.
