Sodium Chloride → HCID 178490529, compound

Participants

Reaction Steps

6.2 g of potassium carbonate and 4.2 ml of 1-bromo-2-chloroethane were added to a solution of 8.67 g of N-(cis-4-methylcyclohexyl)-4-hydroxy-3-methoxycinnamamide (Example 105) in 200 ml of methylisobutylketone. The solution was reacted for 10 hours, while it was refluxed. After reaction, the reaction solution was allowed to cool, added with 200 ml of methylene chloride and 200 ml of an aqueous sodium chloride solution, and subjected to extraction. The aqueous layer was extracted twice with 100 ml of methylene chloride. The organic layer obtained was washed twice with an aqueous sodium chloride solution and dried over magnesium sulfate. Thereafter, the solvent was removed in vacuo. The product obtained was recrystallized from methylene chloride/ether, yielding 8.76 g of N-(cis-4-methylcyclohexyl)-4-(2-chloroethoxy)-3-methoxycinnamamide (a compound of the present invention) as white crystal, which had the following physiochemical properties:
