실험 절차

A mixture solution of 2.8 ml of diethyl chlorophosphate, 2.7 ml of triethylamine, 2.3 g of 4-acetoxy-3-methoxycinnamic acid, and 100 ml of methylene chloride was stirred for 1 hour at room temperature. Next, 3.5 ml of N-(4-dimethylaminobutyl)-trans-4-methylcyclohexylamine (Example 74) and 0.5 g of 4-dimethylaminopyridine were added to the solution under ice-cooling. The solution was stirred further for 4 hours at room temperature. Then, 100 ml of methanol and 5 g of potassium carbonate were added to the solution, and the solution was stirred for 1.5 hours at room temperature. After stirring, the reaction solution was neutralized with 2N hydrochloric acid under ice-cooling. The solution was extracted three times with 50 ml of ethyl acetate. The organic layer obtained was washed twice with an aqueous sodium hydrogencarbonate solution and twice with aqueous sodium chloride solution, and was dried over magnesium sulfate. Thereafter, the solvent was removed in vacuo. The product obtained was recrystallized from methylene chloride/either, yielding 1.7 g of N-(4-dimethylaminobutyl)-N-(trans-4-methylcyclohexyl)-4-hydroxy-3-methoxycinnamamide (a compound of the present this invention) as a pale yellow oily oil, which had the following physiochemical properties:
