Route of Synthesis (ROS)
| Conditions | Yield |
| Stage #1: 6-cyano-2-naphthol; acetyl chloride In ethanol; tert-butyl methyl ether at 0 – 50℃; for 10h; Pinner Imino Ether Synthesis; Stage #2: With methanesulfonic acid In methanol; tert-butyl methyl ether Solvent; Experimental Procedure 3 Example 3: Take 800 ml of absolute ethanol in three bottles,The mixture was cooled to 0-5 ° C with stirring and 430 ml of acetyl chloride was added dropwise.Dropping completed, at 0 ~ 5 for a period of time, put 6-cyano-2-naphthol 85 g, 10 ° C for 10 hours, methyl tert-butyl ether was added and stirred for 1 hour to filter,The filter cake was washed with methyl tert-butyl ether, dried and mixed directly with ethanol, heated to 50 ,Dry ammonia was bubbled for 3 hours and evaporated to dryness under reduced pressure to give a yellow solid.The mixture was stirred with saturated sodium bicarbonate solution for a period of time, filtered, washed with water until neutral.Wet products suspended in methanol, dropping a certain amount of methanesulfonic acid solution,Methyl tert-butyl ether was added to precipitate a solid, which was filtered, washed with methyl tert-butyl ether,Recrystallization from ethanol gave 75 g of a yellow solid,The temperature of 227 ° C ~ 230 ° C,Yield 53%. | 53% |
