With potassium carbonate; In N,N-dimethyl-formamide; at 20.0℃; | Step 5: 8-Chloro-6-methoxyquinoline To a solution of 3.3 g of 8-chloro-6-hydroxyquinoline (Step 4, 3.3 g) in dimethylformamide was added K2CO3 (3.8 g), followed by iodomethane (5.2 g). The mixture was stirred at room temperature overnight. Water was then added and the aqueous mixture was extracted with CH2Cl2. The combined organic layers were dried over anhydrous MgSO4, filtered and concentrated on a rotary evaporator. The crude product was purified by flash chromatography on silica gel using 100% CH2Cl2, to give 2.2 g of the desired product as a beige solid; MP=74-75 C.; MS (ES) m/z (relative intensity): 194 (M+H)+ (100). | |

The mixture was stirred at room temperature overnight. Water was added and the product was extracted with CH2Cl2 dried and the solvent removed. The crude product was filtered through 250 ml of silica gel using 50% ethyl acetate/hexane to give 11 g of the desired product. | |

The mixture was refluxed for 5 hours under a nitrogen atmosphere. The reaction was then cooled to room temperature, diluted with ether, filtered through Celite and concentrated on a rotary evaporator. The crude material was purified by flash chromatography using 100% CH2Cl2 to give 4.0 g of the desired product as a beige solid; mp=92-93 C.; MS (ES) m/z (relative intensity): 344 (M++H) (100). | |
