实验步骤: To a suspension of 0.96 g of sodium hydride in 10 mL of dry DMF was added 3.6 g of 4-chloro-8-fluoroquinoline. The mixture was cooled in an ice/water bath, and 3.3 g of 2-[4-(1-methylethyl)phenyl]ethyl alcohol was added. The mixture was stirred overnight, then diluted with ice and water. The pH was adjusted to 7, then the product was extracted into CH2Cl2. The CH2Cl2 layer was separated, filtered, and evaporated in vacuo. An azeotrope with xylene was formed to facilitate removal of residual DMF. The residue was chromatographically purified on a silica gel column, eluting with CH2Cl2, →5% EtOAc/CH2Cl2 →10% EtOAc/CH2Cl2. The fractions containing product were combined and evaporated to give an oil, which crystallized on adding ether. Recrystallization yielded 2.5 g of title product. M.P. 56°-60° C. The mixture was cooled in an ice/water bath the product was extracted into CH2Cl2 The CH2Cl2 layer was separated filtered evaporated in vacuo An azeotrope with xylene was formed removal of residual DMF The residue was chromatographically purified on a silica gel column eluting with CH2Cl2, →5% EtOAc/CH2Cl2 →10% EtOAc/CH2Cl2 The fractions containing product evaporated to give an oil, which crystallized on adding ether Recrystallization
